A Reactance Target Simulator

Abstract

In the reactance target simulator disclosed by the present invention, the main control unit of the system is used to receive signal parameter settings and output control instructions to the interface control component, and the interface control component analyzes the control instructions and outputs control codes to the narrowband source module, baseband source module, Frequency extension module; narrowband source module outputs CD signal, several diversity signals and 2 reference signals; baseband source module receives control code and one reference signal output by narrowband source module, and outputs baseband signal; frequency extension module receives control code, baseband source The baseband signal output by the module and another reference signal output by the narrowband source module output a frequency source signal; the combining component receives the diversity signal output by the narrowband source module and / or the frequency source signal output by the frequency extension module, and outputs a ratio signal and interferometer signals. The invention can generate diversified signal forms, high fidelity, high precision and stable radar signals 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...

AI Technical Summary

Problems solved by technology

The traditional electronic countermeasure simulator is based on a single radar signal for analog output. The analog waveform is simple, the signal density is low, and the frequency band coverage is small, which cannot meet the existing needs for electronic countermeasure equipment under increasingly complex electromagnetic environment conditions.
