Abstract

According to the reactance target simulator disclosed by the invention, a system main control unit is used for receiving signal parameter setting and outputting a control instruction to an interface control assembly, and the interface control assembly analyzes the control instruction and outputs a control code to a narrowband source module, a baseband source module and a frequency expansion module respectively; the narrowband source module outputs a CD signal, a plurality of diversity signals and two reference signals; the baseband source module receives the control code and one path of reference signal output by the narrowband source module, and outputs a baseband signal; the frequency expansion module receives the control code, the baseband signal output by the baseband source module and the other path of reference signal output by the narrowband source module, and outputs one path of frequency source signal; and a combining assembly receives diversity signals output by the narrowband source module and/or frequency source signals output by the frequency extension module, and outputs amplitude comparison signals and interferometer signals. According to the invention, diversified signal forms and high-fidelity, high-precision and stable radar signals can be generated in real time.

Description

technical field [0001] The invention relates to the technical field of signal simulators, in particular to a reactance target simulator. Background technique [0002] The reactive target simulator is a real-time simulation system composed of multiple subsystems. The system can simulate simple or complex radar pulse signals of different types of airborne radars, so as to complete injection and radiation real-time tests of electronic countermeasure equipment. Complex signal simulation generation equipment (also known as simulator host) is the core equipment of the entire electronic countermeasure simulation system. It can complete various signal simulations under different radar systems according to requirements, and complete various complex signal simulations with the cooperation of other subsystems. Simulation tests of institutional radar signals. [0003] The role of electronic warfare in modern warfare is becoming more and more important. Countries are now paying more and...
