Abstract

The invention relates to the technical field of radar testing, in particular to a radar radiating source simulator. The invention aims to solve the problem of limitation of a single-system single-radar radiating source. Therefore, the radar radiating source simulator disclosed by the invention comprises a modulation source module, an agile source module, a frequency mixing and filtering module, a radio frequency sending module and a signal processing and control module, wherein the modulation source module is used for generating a C-waveband output signal; the agile source module is used for generating a 11-17GHz radio frequency output signal; the frequency mixing and filtering module is used for receiving the output signals generated by the modulation source module and the agile source module and outputting a 6-18GHz radio frequency output signal; the radio frequency sending module is used for processing the 6-18GHz radio frequency output signal to generate a 0.8-18GHz radio frequency output signal of the radar radiating source simulator; and the signal processing and control module is used for carrying out upper control and coordination of the radar radiating source simulator. The radar radiating source simulator is a multi-system radar radiating source simulator. The broadband radio frequency output signal can be output. The limitation of the single-system single-radar radiating source is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of radar testing, in particular to a multi-system radar radiation source simulator. Background technique [0002] The multi-system radar radiation source simulator is a laboratory and field test equipment equipped with passive radar guidance systems. It can test various functions and performance technical indicators such as search and tracking accuracy, range and sensitivity of passive radars. It is an important technology for evaluating passive radars. The standard equipment of the index, which can also test the anti-jamming ability of the active radar. Passive radar testing requires a radar signal simulator capable of simulating a variety of radar emission signals and the space electromagnetic environment. It can simulate radar antenna scanning and simultaneously simulate multiple radars. Existing passive radar signal sources mainly have a single function, or have a single system, or have insufficient fre...
