A method for realizing multi-target jamming based on repetition frequency tracker

Abstract

The method for realizing multi-target jamming based on the repeater frequency tracker disclosed in the present invention is divided into reconnaissance, search and tracking jamming stages, switches to the reconnaissance mode at regular intervals, completes signal sorting and compares with the preset radar library, and binds the radars that need to be jammed. parameters; in the search stage, the bound radar parameters are used to perform repeated frequency tracking on multiple radars, and the predicted sampling gate and the predicted jamming gate are output to guide the jamming; in the tracking jamming stage, the jamming is reasonably allocated according to the tracking results and the priority of each radar. Resource; when the reconnaissance, search, and tracking interference effect is not good, switch to degradation mode. The degradation mode adopts the method of regularly switching sampling and interference gate. The radar pulse detected in the sampling gate will be sampled and stored. Cast a distraction. The invention utilizes the repetition frequency tracker to predict the pulse arrival time of the target radar, guides the interference more accurately, and can adaptively adjust the interference mode according to the reconnaissance, tracking and interference states.

Description

technical field [0001] The invention relates to the technical field of radar jamming, in particular to a multi-target jamming implementation method based on a repetitive frequency tracker. Background technique [0002] In radar electronic warfare, with the increasingly complex electromagnetic environment, multiple systems and multiple radars working at the same time, the pulse repetition frequency, carrier frequency, pulse width and other rapid changes, the radar jamming system how to accurately interfere with the target radar and adaptive allocation Interference resources present new challenges. The traditional jamming method uses the method of timing switching sampling and jamming gate, sampling and storing the pulse in the sampling gate, and transmitting the jamming in the jamming gate. This method cannot predict the arrival time of the pulse, and it is easy to miss the pulse. affect the interference effect. Re-frequency trackers can quickly capture targets in complex e...
