Low-cost radar seeker semi-physical simulation test platform

Abstract

The invention relates to a low-cost radar seeker semi-physical simulation test platform. The low-cost radar seeker semi-physical simulation test platform comprises a radar seeker, a turntable, a simulation computer, a target echo signal simulator, a target motion control system, a power amplifier component, a waveguide stimulation head, a FPGA (Field Programmable Gate Array) delay trigger module, a signal source and a target motion bracket, wherein the radar seeker is mounted on the turntable, the turntable is in control connection with the simulation computer, the target echo signal simulator is connected with the simulation computer, and the target motion control system, the power amplifier component and the waveguide stimulation head are connected. Compared with a common radio frequency semi-physical simulation test platform, the low-cost radar seeker semi-physical simulation test platform saves an anechoic chamber and radio frequency store-and-forward equipment, the simulation and test costs are greatly lowered, the construction period of a test system is shortened, and the development condition of the radar seeker and the development efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of radar seeker hardware-in-the-loop simulation tests, in particular to a low-cost radar seeker hardware-in-the-loop simulation test platform. Background technique [0002] In the development stage of the radar seeker, a large number of simulation tests are required to verify its detection, search, capture and tracking performance. Since the performance index of the radar seeker needs to be verified by a large number of field experiments, the conditions of the field test are very harsh, the efficiency is low, and the target environment cannot be repeated, which is not conducive to the analysis, judgment, and solution of the technical problems of the radar seeker. At the same time, the field experiment The cost is also relatively high. Half-in-the-loop simulation technology provides an effective means to solve these problems. [0003] In traditional applications, the hardware-in-the-loop simula...
