Abstract

The invention discloses an active-passive integrated anti-jamming radar device. The active-passive integrated anti-jamming device comprises a casing, a radar body, a power module, a receiver, a display module, a control processing module, a signal processing module, a passive anti-jamming module and an active anti-jamming module, wherein the radar body comprises exploring antennae, a T/R assemblyand a power divider and magic-T unit; the active anti-jamming module comprises a transmitting waveform generation module, a frequency synthesizer and a jamming detection module. Active anti-jamming capacity is added on the basis of passive anti-jamming measures of a radar, different radar transmitting waveforms are selected according to the electromagnetic environment where the radar works, the radar waveforms with different repetition frequency are transmitted, radar cover pulses are transmitted, and the active anti-jamming capacity of the radar is improved in the aspect of transmitted signalwaveforms; interfering frequency around the radar is sensed by the jamming detection module, so that working frequency point of the radar is changed in real time, the interfering frequency is avoided, and the active anti-jamming capacity of the radar is improved.

Description

technical field [0001] The invention relates to the technical field of radar anti-jamming, in particular to an active-passive integrated anti-jamming radar device. Background technique [0002] In recent years, with the rapid development of electronic jamming technology, the working electromagnetic environment faced by modern radars has become increasingly complex. In particular, the rapid development of radar jamming technology in recent years poses a serious threat to traditional radar due to its characteristics of multiple styles, flexible use, and strong confrontation. In order to cope with the above-mentioned threats, most modern radars adopt certain anti-jamming measures, mainly including: low sidelobe antenna, frequency agility, pulse compression, MTD, etc. If the radar is interfered, the radar will take certain anti-jamming measures for radar countermeasures. [0003] However, the above-mentioned anti-jamming technology adopted by the radar is mainly considered fro...
