5.1. Preface
This chapter describes the specifications to install 24 GHz radar sensors into vehicles.

These specifications shall be complied with to enable the specified characteristics of the
sensors as well as the complete system. Due to the various installation situations and
applications, a measurement check is required to verify the actual installation
implementation.

5.2. 24 GHz Sensors

This chapter describes the characteristics relevant to the installation of 24 GHz sensors
in vehicles. Note that there are three types of 24 GHz sensors, each supporting
various applications as follows:

24 GHz Mid Range Radar (MRR) – used of medium range applications 24 GHz Short
Range Radar (SRR) – used of short range applications 24 GHz Multi Mode sensor
(MMS) – combined SRR and MRR functionality.

Unless otherwise stated the specifications contained in this document apply to all 24
GHz sensor types.

In addition general specifications are mentioned, which have to be followed for each
position to enable sufficient sensor performance. Therefore the following guidelines are
to be observed very carefully. See annex for performance measurements.

IMPORTANT NOTE

: The two mounting holes are not specified for mounting the complete sensor. They do not provide the
mechanical properties to keep the sensor in place. They shall be used to fix the sensor in a mounting bracket. Mounting tabs
are to be fastened tight to mounting bracket using appropriate fastener. Maximum strength per tab is 270 N.

5.2 24 GHz Sensor (cont’d)

5.2.2 Keep-Out Zone / Azimuth Angle Measurement Range
Figure 2 displays the keep out area of the 24 GHz sensor.
Within the detection area of the antennas there must not be objects like screws,

mounting brackets, license plates etc. The impact reducing foam material, clips
or fascia laminations has to be avoided in that area.

Within the keep out zone of the antennas there must be no vertical character
lines present in the fascia. Mounting bracket material shall not enter the non­conductive keep out zone. Bracket retention features which interface with the
surface of the sensor radome shall not enter the keep out zone noted in Section

5.2.5
The keep out zone in the azimuth direction is ±45°. The angle is established

7mm from the edge of the sensor.

Note: For blind spot applications the keep out zone in the azimuth direction shall
be ±65°.
