Multiprobe Radiation Simulation Method for Phased Array Radar Performance Evaluation

Abstract

The phased array radar exhibits improved tracking accuracy and anti-jamming performance with multi-beam tracking, beam agility, and adaptive beam-forming capabilities. The performance evaluation of the phased array radar is essential for the product designing and development stage. However, the conventional injection simulation and triad radiation simulation methods are not suitable for phased array radars. Therefore, new methods for radiation simulation are required on an urgent basis for the performance evaluation of phased array radars in a reliable, reliable, and repeatable way. This paper focuses on designing a practical anechoic chamber system of multi-probe radiation suitable for phased array radars. The appropriate test distance, the physical size of the anechoic chamber, the multi-probe radiation signal model, and the number of probes required were discussed. Furthermore, an inversion method based on least squares was proposed to solve the complex weights of the probes, thereby simulating the desired apparent center position. The simulation results demonstrated the effectiveness of the proposed method.
