How to run a simulation of raw radar data on a computer

摘要

Disclose a method for simulating raw radar data executed by a computer. The raw radar data includes a transmitter array (2) of a plurality of transmitters (201,202) for transmitting a radar signal and a receiver array (3) of a plurality of receivers (301,302) for receiving a radar echo of a radar signal. Generated for synthetic MIMO radar system (1) including. A radar signal sent from a preset transmit position (TP) in the transmitter array and received at a preset receive position (RP) in the receiver array based on a 3D model of the virtual region (AR) adjacent to the MIMO radar system. Perform ray tracing. Ray tracing determines the propagation of multiple rays (R1, R2, R3) in the radar signal from the preset transmit position to the preset receive position, and each ray propagation describes the direction of each ray at the preset transmit position. It depends on the first angle θ and the second angle φ. By using the first derivative with respect to the angles θ and φ, the propagation of multiple modified rays originating from each transmitter and received by each receiver is determined based on a linear approximation. The modified rays are processed to determine the radar raw data.
