[0075] Example 1
[0076] This embodiment provides a 96-channel distributed target echo simulation intermediate frequency system that is directly applied to the intermediate frequency echo simulation of the 96-element digital array radar system. It is composed of a high-performance processing circuit with a VPX 6U structure and multiple high-speed DAC array circuits. Based on the high-efficiency and compact system architecture, it generates the intermediate frequency echo of a multi-channel digital array radar distributed target based on the multi-scattering point model.
[0077] figure 1 The flow chart of the simulation method is given, including the following steps:
[0078] S01: Calculate the Doppler frequency f caused by the geometric center of the distributed target without considering the spin characteristics and the radial velocity of the radar d Time delay τ caused by distance and distance;
[0079] S02: Calculate the one-dimensional range image in the radial direction accordi...
