Patent ID: 11585893

Abstract:
A multi-target dynamic simulation test system for vehicle-mounted millimeter-wave (MMW) radar. The test system includes an antenna turntable, a radar pan-and-tilt head (PTH), a radar echo simulation module, a control module, a signal acquisition module and a display. A test radar is driven by the radar PTH to pan or tilt. The radar PTH and the test radar are both placed in a darkroom module. An antenna is driven by the antenna turntable to pan. The control module sends expected states of the test radar and the antennas to the radar PTH and the antenna turntable, respectively, and sends relative states between host vehicle and virtual targets to the test radar after processing by the radar echo simulation module. The signal acquisition module acquires and stores a detection signal of the test radar, and transmits the detection signal of the test radar to the display for real-time display.
