Distance2GoL (Software-Controlled FMCW) low-power radar shield using
BGT24LTR11 for range detection and human tracking
Introduction
1.2

Key features

The primary features of the Distance2GoL radar system are as follows:
• Detects distance of a human in a user-configurable range (1 to 15 m)
•
Detects distance and velocity of the closest human or moving target
• Low power consumption
• Two-board topology for RF section and microcontroller sections
•
Two customizable analog amplifier stages for the RX channel
• Micro-strip patch antennas with 10 dBi gain and 29 x 80 degree Field of View (FoV)
• Multiple power supply possibilities – micro-USB, external power supply or LiPo battery
•
Compatible with Arduino for ease of use and prototyping
•
Operates in different weather conditions, including rain, fog, etc.
• Can be hidden in the end application as it detects through non-metallic materials
Note: The platform serves as a demonstrator platform with the software to perform simple motion sensing. The
test data in this document show typical performance of Infineon-produced platforms. However, board
performance may vary depending on the PCB manufacturer and specific design rules imposed and
components used.

Overview

The platform is a stack-up of two boards – BGT24LTR11 Shield (radar front end) and radar baseboard XMC4700
(for signal processing).
The Distance2GoL radar system consists of the following key components:
• BGT24LTR11 – highly integrated 24 GHz transceiver IC with one transmitter (TX) and one receiver (RX)
• XMC4700 – 32-bit ARM® Cortex®-M4 based microcontroller for signal processing
•
IRLHS2242 – 20 V single P-channelMOSFETs for duty-cycle operation
•
MCP73831T – battery manager for charging and using the battery
• CW1280T – EEPROM to store board identifier information
•
MOLEX 047571001 – SD card reader for storing raw data
•
XMC4200 –32-bit ARM® Cortex®-M4 based microcontroller for debugging
