Abstract
Disclosed herein is a radar target simulator (RTS) device including a processor and a memory. The memory stores computer-readable instructions that, when executed by the processor, cause the processor to perform acts including receiving a test sensor probe signal from a test sensor. The acts further include generating a first virtual target for a radar target simulation and transmitting a virtually reflected waveform responsive to the test sensor probe signal for the radar target test simulation, wherein the virtually reflected waveform is based at least in part on a change in a position of the first virtual target.
Claims19
A radar target simulator (RTS) device, comprising:
- a processor;
- and
- memory that stores computer-readable instructions that, when executed by the processor, cause the processor to perform acts comprising:
- receiving a test sensor probe signal from a test sensor, wherein the test sensor probe signal comprises one or more chirps, wherein each chirp comprises a continuous change in frequency over time;
- generating a first virtual target for a radar target test simulation;
- generating, based at least in part on a change in a position of the first virtual target, a virtually reflected waveform by time shifting the test sensor probe signal according to per-frame position information of the first virtual target to account for range migration across and within the one or more chirps;
- and
- transmitting, responsive to the test sensor probe signal for the radar target test simulation, the virtually reflected waveform with a forward or a backward transmission time relative to receipt of the test sensor probe signal under control of a synchronized or triggered RTS clock.
A method of simulating a radar target detection comprising:
- receiving a test sensor probe signal from a test sensor, wherein the test sensor probe signal comprises one or more chirps, wherein each chirp comprises a continuous change in frequency over time;
- generating a first virtual target for a radar target test simulation;
- generating, based at least in part on a change in a position of the first virtual target, a virtually reflected waveform by time shifting the test sensor probe signal according to per-frame position information of the first virtual target to account for range migration across and within the one or more chirps;
- and
- transmitting, responsive to the test sensor probe signal for the radar target test simulation, the virtually reflected waveform with a forward or a backward transmission time relative to receipt of the test sensor probe signal under control of a synchronized or triggered RTS clock.
