Abstract

Abstract:

Radar hardware-in-the-loop (HWIL) simulation has the advantages of low cost, high flexibility and good confidentiality. However, because the radar mode and processing are complex increasingly and the target altitude is gradually changeable, the radar HWIL simulation is facing various challenges such as the pulse signal equivalent simulation in anechoic chamber and the high-fidelity simulation of target dynamic characteristic. In the aspects of radio frequency injection simulation and radiation simulation, the development of radar HWIL simulation, the technical features and implementation difficulties of radar HWIL simulation are summarized. The key technologies of the radar radiation simulation, such as the anechoic chamber design problem, near-field experiment problem and target characteristics simulation and measurement method are mainly discussed. Furthermore, the bottleneck problems and solutions of pulse radar radiation simulation in anechoic chamber are analyzed, aiming to provide reference and basis for the future research of radar HWIL simulation.

Key words: radar hardware-in-the-loop (HWIL) simulation, injection simulation, radiation simulation, pulse radar, target measurement
