INTRODUCTION

This document is a short documentation of the general purpose universal medium range radar (UMRR) UMRR-9F Type 169 radar sensor with type 169 antenna.

GENERAL DESCRIPTION

1. SENSOR SPECIFICATIONS
DRVEGRD 169 is a 79GHz radar sensor for multiple automotive applications that features 4D/PxHD technology.
The sensor’s antenna aims at ultra-short, short and medium range and very wide horizontal angular coverage. It features:
A straight beam with wide field of view
Selectable modes: ultra-short-, short-, medium- and long-range mode
2. MEASUREMENT PRINCIPLE
Using a patented transmit waveform, the sensor measures range, radial speed, azimuth angle, elevation angle, reflectivity and more parameters of multiple stationary and moving reflectors (targets) simultaneously. It is capable of ultra-high definition (4D/PxHD), where PxHD resolution means that the sensor features resolution (separation) in three parameters: range, Doppler, and azimuth angle.
The sensor is almost unaffected by weather, temperature, and lighting conditions. It withstands high shock and vibration levels, is maintenance-free and made for a long lifetime.
4D/PXHD MEASUREMENT
A 4D Doppler based radial motion detection principle is integrated:
a) Direct unambiguous Doppler measurement (speed)
b) Direct range measurement
c) Direct azimuth angle measurement (horizontal angle)
d) Direct elevation angle measurement (vertical angle)
Moving reflectors can be detected as well as stationary reflectors.
With its multi-target capability, the sensor can detect many reflectors within the field of view at a time (target list = point cloud). Additionally, optional filter algorithms are implemented for certain applications for the tracking of all detected reflectors over time. Those tracking algorithms are integrated in the sensor. Multiple objects can be tracked simultaneously.
The result of tracking is an object list with the following parameters:

In addition, status and diagnose data from the sensor are reported. The sensor optionally reports such a list of all tracked objects in every measurement cycle of typically ~55ms length. Based on all detected targets and tracked objects within the field of view an application algorithm, such as blind spot warning, lane change assist or collision warning, may be implemented.
PIXEL-HIGH DEFINITION RESOLUTION – OBJECT SEPARATION PERFORMANCE
The sensor divides the field of view into range gates and performs a Doppler (speed) measurement separate for each individual range gate.
Individual reflectors are separated by detection algorithms if having either:
A different radial speed value or
A different range value or
A different azimuth angular position
USER CONFIGURABILITY
The operational mode and frequency band are user-configurable:
The sensor allows to switch between short-range mode, medium-range mode and long-range mode. The modes differ regarding the waveform and the detection performance.
There are three user-configurable frequency bands. These frequency bands are non-overlapping in long and Medium-Range Mode, so that the mutual interference can be reliably avoided. In Short-Range Mode and Ultra-Short-Range Mode, the bands will partly overlap.
The Long-Range Mode can be used for applications like Lane Change Assist (LCA(C)), Blind Spot Detection (BSD), Rear Cross Traffic Alert (RCTA), or Exit Assistant, whereas the Medium-Range Mode can be used for Rear or Front Cross Traffic Alert (RCTA/FCTA) applications. The Short Range Mode can be applied for Parking Search and the Ultra-Short-Range Mode for Parking.¹
¹An application-specific tracking or sensor data fusion is required.
4.1 TRANSMIT SIGNAL
The UMRR transmit frequency is in the band from 77 GHz to 81 GHz, the used bandwidth is less than 4 GHz. The maximum transmit power is +26 dBm.
Antenna type 169 consists of three transmit and four receive antennas, which are linear polarized.
The Tx0 and Tx1 have the same antenna characteristics but different center position on the board. The Tx2 squints in azimuth with -30° comparing to Tx0 and Tx1. The 2-way 20 dB cut-off angle in azimuth (Az.) and 6dB cut-off angle in elevation (El.).
The device uses different FMCW transmit signal waveforms for distance and speed measurement.
4.2 GENERAL PERFORMANCE DATA
After power on or reset, the sensor readings are within specified performance within <4 seconds.
In Table 4-1 the general performance data of UMRR-9F Type 169 are given.

Please note that in the standard configuration the sensor has 120 Ohms resistor on board (CAN bus termination between CAN_L and CAN_H). A number of cable sets for initial operation and test purposes are offered by Smartmicro, to deliver a fast set-up of a sensor system.

DATA INTERFACES

7.1 CAN DATA INTERFACE
This specification gives a detailed description of the CAN data communication used in the UMRR based systems on the sensor CAN. The UMRR is compliant with CAN 2.0B standard.
CAN is a very robust full duplex bidirectional interface.
7.2 CAN-SETTINGS

(SJW: synchronization jump width)
Above values for CAN bit timing are illustrated in Figure 7-1 used in the UMRR radar sensor ( note:  the CAN module is integrated in the DSP). For comparison purposes, in Figure 7-2 the CAN bit timing as defined by the CAN protocol is shown.
The CAN bit timing parts as defined by the CAN protocol (Figure 7-2) can be described as follows:

• Sync: This part of bit time is used to synchronize the various nodes on the bus. An edge is expected to lie within this segment. For the UMRR sensor, this segment is always 1 TIME QUANTUM (TQ).
• Prop: This part of the bit time is used to compensate for the physical delay times within the network. It is twice the sum of the signal’s propagation time on the bus line, the input comparator delay, and the output driver delay. For the UMRR sensor, this segment is programmable from 1 to 8 TIME QUANTA (TQ).
• Phase 1: This phase is used to compensate for positive edge phase error. For the UMRR sensor, this segment is programmable from 1 to 8 TIME QUANTA (TQ) and can be lengthened by resynchronization.

Phase 2: This phase is used to compensate for negative edge phase error. For the UMRR sensor, this segment is programmable from 2 to 8 TIME QUANTA (TQ) and can be shortened by resynchronization

APPLICATION-SPECIFIC CHARACTERISTICS

The sensor can be used for different applications by using either point cloud, tracking or collision avoidance firmware.
FUNCTIONAL SAFETY
The sensor can optionally be made compliant to ASIL Level B in customer- specific projects. Requirements and safety concepts need to be agreed between an OEM and smartmicro.
AUTOSAR
The sensor is offered with AUTOSAR compliant software in customer-specific projects.
Specifications need to be agreed between an OEM and smartmicro.
8.1 POINT CLOUD
Using the point cloud firmware, the sensor can be used for long-, medium-, short, and ultra-shortrange applications in autonomous driving systems, for example:

• Autonomous driving
• Blind Spot Detection (BSD)
• Lane Change Assist (LCA)
• Forward Collision Warning (FCW)
• Side Collision Warning (SCW)
• Rear Collision Warning (RCW)
• Rear Cross Traffic Alert (RCTA)
• Front Cross Traffic Alert (FCTA)
• Exit Assistant or Door Open Warning (DOW)
• Parking Assistance
• All kinds of 360-degree applications

One or multiple sensors may be integrated into vehicle models by OEMs. Usually, certain OEM specific engineering efforts are required for the adaptation to specific vehicle models as well as the application of test and qualification procedures. Customer-specific connectors, CAN(FD) or Ethernet interfaces, tracking algorithms, warning algorithms or other software packages can be included.
