Problems solved by technology

As far as the space electromagnetic environment is concerned, after multiple radars are networked, not only the number of radiation sources will increase, making the density and distribution of the signal space more complex, but also the reconnaissance system will be affected in terms of frequency range, signal form, parameter type and threat level. come difficult, so that the interference quality is greatly limited

Abstract

The invention, which belongs to the field of the anti-interference technology of the radar, discloses an optimized station distribution method for a netted radar unit under deceptive jamming. The method comprises: a deceived probability of a netted radar is calculated; a target function of a minimized deceived probability is constructed; coverage ranges of all node radars in the netted radar unit are calculated and a target function of a maximized coverage range is constructed; according to the target function of the minimized deceived probability and the target function of the maximized coverage range, a combined optimized target function is established; a constraint condition of station distribution of the netted radar unit is determined; on the basis of the constraint condition of station distribution of the netted radar unit and the combined optimized target function, an optimization formula of station distribution of the netted radar unit is constructed under deceptive jamming; and station distribution positions of all node radars in the netted radar unit are obtained based on the optimization formula of the station distribution of the netted radar unit under deceptive jamming. Therefore, the radar system resources are saved and precise and effective inhibition of the deceptive jamming can be realized.

Description

technical field [0001] The present invention relates to the field of radar anti-jamming technology, and in particular to a method for optimizing station deployment of networked radars under deceptive interference. The location of the networked radar is obtained, so as to improve the ability of the networked radar to suppress deceptive interference. Background technique [0002] Deceptive interference refers to the indistinguishability between the interference signal and the target echo signal in the radar receiver, so that the radar cannot correctly detect the target information. The working principle of deceptive jamming is: transmit signals to the received radar, after interference modulation, change the relevant parameters, and then forward the modulated signal back to the radar to simulate the echo signal of the radar target. It makes it difficult for the radar to distinguish between true and false targets, thereby achieving the purpose of confusing and disrupting the r...
