Ultra-wideband radar signal jamming simulator

Abstract

The invention relates to the field of radar and electronic countermeasures, and discloses an ultra-wideband radar signal jamming simulator. The ultra-wideband radar signal jamming simulator comprisesan ultra-wideband receiver, a detection processing module (DRFM), a jamming strategy module and a broadband debugging module, wherein the ultra-wideband receiver performs amplification, channel selection and mixing on a broadband radio frequency signal to obtain a broadband baseband signal; an input end of the detection processing module is connected to an output end of the ultra-wideband receiverso as to perform high-speed digital sampling and discrimination processing to obtain a signal A, and the signal A is recorded and stored in real time; the jamming strategy module is a preset electronic countermeasure expert database, can carry out oppressive jamming, deception jamming and combined jamming on a target according to requirements and forms a wide baseband data waveform (B); and the broadband debugging module receives a wide baseband signal containing the jamming strategy, performs broadband debugging to convert the wide baseband signal into radio frequency, then performs filtering and broadband linear power amplification and sends out the radio frequency. The ultra-wideband radar signal jamming simulator greatly promotes the anti-jamming ability of the radar signal.

Description

technical field [0001] The invention relates to the field of radar and electronic countermeasures, in particular to an ultra-wideband radar signal jamming simulator. Background technique [0002] In future wars, electronic warfare will be used as the main means of confrontation and will be widely used. As the main perception and detection equipment for defending positions, the radar system can track multiple targets in the airspace, identify true and false targets, and strike key targets, etc., which is crucial for the radar system to improve its combat capability and wartime survivability Characteristics, to some extent, determine the success or failure of the war. [0003] However, there are not many researches on ultra-wideband at present, and it is impossible to provide radar signal jamming with ultra-wideband and combined jamming strategies. Contents of the invention [0004] The purpose of the present invention is to provide a kind of UWB radar signal jamming simul...
