Abstract

The invention discloses a track deception jamming system and a track deception jamming method for an airborne early-warning PD radar. The track deception jamming system comprises a receiving antenna,a transmitting antenna, an amplifier, a high-frequency shunt circuit, a radio frequency storage broadening module, a high-sensitivity receiving branch circuit, a pulse delay module, a low-sensitivityreceiving branch circuit, a square wave delay module, a square wave shaping module, a pulse gating module, a pulse modulation module, a microwave signal power amplification module and a power supply module. Through the design of two groups of track false targets related to radar signal repetition frequency, false tracks can be generated in front, back, left and right directions of a jammer and a shield target, and the purpose of supporting jamming is achieved.

Description

technical field [0001] The invention belongs to electronic anti-jamming technology, in particular to a track deception jamming system and method for airborne early warning PD radar. Background technique [0002] In modern radars, the comprehensive application of various anti-jamming technologies reduces the jamming effect of spoofing jamming of a single parameter. In view of this situation, it is necessary to propose new jamming means to improve the operational effect of electronic jamming. In this context, many new jamming techniques and tactics have been proposed, and track deception jamming is a typical new jamming technique. In peacetime, track deception jamming is carried out on known enemy radars, and their corresponding working parameters can be detected, and hidden radars can also be lured to start up, so as to conduct intelligence collection operations on them; while in wartime, track deception jamming The false targets formed with higher fidelity can occupy the en...
