Embodiment 1

[0036] combine figure 2 , the target fluctuation model of this embodiment is the Swerling II type, which specifically includes the following steps:

[0037] Step 1. According to the parameter characteristics of the simulated radar target, generate a deceptive jamming signal S through existing methods (such as forwarding delay, Doppler frequency shift, etc.) f , record its power as P jr .

[0038] The generated deceptive interference signal is obtained by processing the collected radar signal. For example, the distance deception can be carried out by delaying the transmission of the collected radar pulse signal, and the frequency shift of the collected radar pulse signal can be carried out. Speed ​​cheats. The specific generation method can be selected according to the actual application, and the interference signal parameters are set according to the simulated radar target parameters.

[0039] Step 2. Estimate the amplitude adjustment factor α according to the movement di...

Abstract

The invention discloses a simulation radar target simulation method based on power. The method comprises the steps: firstly, according to parameter characteristics of a simulation radar target, generating a fraudulent interference signal Sf through a forwarding delay or Doppler frequency shift method, and recording the power of the fraudulent interference signal Sf as Pjr; estimating an amplitudeadjustment factor [alpha]f according to the motion distance characteristic of the simulation radar target and a target fluctuation model; and finally, modulating the transmitting power Pjt of the deceptive interference signal Sf in real time according to the amplitude adjustment factor [alpha]f, wherein Pjt=[alpha]f<2 >*Pjr. The method is simple and easy to implement, and the deception effect of the simulation radar target is improved.

Description

technical field [0001] The invention relates to the technical field of radar jamming, in particular to a power-based simulated radar target simulation method. Background technique [0002] In modern warfare, radar occupies an indispensable position. Deceptive jamming uses false target parameters to act on the radar system by transmitting jamming signals, so that the radar cannot correctly detect the real target parameters, so as to confuse and disrupt the enemy's radar and protect our targets. [0003] The current deceptive jamming mainly interferes with the radar from parameters such as distance (forwarding delay) and speed (Doppler frequency shift), but rarely deceptively adjusts the jamming power, which is consistent with the echo power characteristics of the real target. Distinct, and will obviously reduce the deceptive effect of jamming. Liu Congfeng et al. proposed a method for estimating the transmission power of spoofing jamming signals, but it did not take into ac...
