Radar Manual & Integrator Instructions

These module integration instructions provide OEM integrator instructions for using the Patroness RADAR module. Please review and understand

the conditions, limitations, and authorized uses of this module prior to integration.

Overview of Module

Figure 1. Patroness RADAR module.

The Patroness RADAR module is a mmWave sensor based on FMCW) radar technology capable offrequency-modulated continuous wave (

operation in the 76- to 81-GHz bandwidth up to 4 GHz continuous chirp. It is built with a Texas Instruments IWR1443 System on Chip (SoC) main

processor and integrated custom 3 Tx, 4 Rx antenna array capable of .generating x,y,z coordinates for up to 100 unique targets in its field of view

Communication with the module is accomplished via . SPI protocol (Serial Peripheral Interface)

The module is intended for integration into non-automobile motorized devices such as powered mobile chairs, mobility scooters, electronic

conveyance vehicles, riding lawn mowers, grocery carts, all-terrain vehicles (ATVs), golf carts, and other mobile systems. It is not intended to be

used in automobiles (passenger cars, trucks, passenger buses, and other passenger or property transporting motorized vehicles intended for

licensed operation on state and national highways) or for fixed applications.

Features

Precise, non-contact target tracking measurement for multiple objects

Low power and data processing requirements compared to competing approaches such as a scanning LIDAR

Easy to use serial interface

RoHS Compliant

Performance Characteristics

The following table describes typical performance characteristics of the default configuration of the Patroness RADAR module. The values given

are based on controlled range testing without any enclosure or housing. Enclosure and mechanical configuration impacts the performance of the

system and integrators should confirm performance for their unique application prior to release.

The module is intended to be mounted in an enclosure for protection against the elements and damage. The board nominal thickness is 1.6 mm. Module Mounting Figure 2. Patroness RADAR module dimensions. Electrical & Communication Interface The interface connector on the RADAR accepts a Molex PN 5054320801 8-Position Rectangular Housing Connector. The pinout is detailed below.

enable signal is released. Once powered for use, the IWR1443 SoC begins running based on the onboard configuration settings and sends target data back to the host over serial protocol. Data is reported out 64 bytes at a time and the host interrupt pin is toggled when data is ready to read. The Patroness RADAR will continue to report data based on a RADAR sampling rate of 12 Hz until the enable pin status is changed or power is lost to the device.

The antenna peak gain is 10.85 dBi across the frequency band of 76 to 81 GHz. The radiation paternities of the antenna in the horizontal plan (H-plane) and elevation plan (E-plane) is shown in Figure 4 and Figure 5. Figure 4.
PAGE 6
Figure 5. Antenna Pattern in E-Plane The beamwidth of the antenna is determined from the radiation patterns described in the previous figures. For example, at 78 GHz, based on a 3-dB drop in the gain as compared to bore sight, the horizontal 3dB-beamwidth is approximately +/-28 degrees (see Figure 4), and elevation 3dB-beamwidth is approximately +/-14 degrees (see Figure 5). Similarly, the horizontal 6dB-beamwidth is approximately +/-50 degrees and the elevation 6dB-beamwidth is approximately +/-20 degrees.
