Embodiment Construction

[0068] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0069] In one embodiment, such as figure 1 As shown, a radar signal optimization method is provided, the method includes the following steps:

[0070] In step 100, two sets of signals generated by different chaotic codes are acquired; one set is a radar emission signal, and the other is an interference signal; both the radar emission signal and the interference signal are MCPC-OFDM radar signals.

[0071] The signals generated by two different chaotic codes are multi-carrier phase coded-orthogonal frequency division multiplexing (Multi-carrier Phased Coded-Orthorgonal Fre...

Abstract

The application relates to a radar signal optimization method, device, computer equipment and storage medium. The method utilizes the initial value sensitivity and pseudo-randomness of chaotic coding, and optimizes the key parameters of the signal waveform by reducing the correlation between adjacent pulse signals. : The number of subcarriers, the number of chips, and the initial value of chaos, etc., and then obtain the radar pulse signal combination method with the best anti-replication and forwarding interference performance. And copied the signal pulse, but the process of identification and copying takes a certain amount of time, and the matching gain cannot be obtained with the subsequent pulse, so it has an excellent ability to resist copying and forwarding interference. This method adopts the waveform optimization method to improve the anti-replication and forwarding interference performance of the radar, does not require additional calculations during signal processing, and is more suitable for engineering applications.

Description

technical field [0001] The present application relates to the technical field of radar communication, in particular to a radar signal optimization method, device, computer equipment and storage medium. Background technique [0002] With the complexity of the battlefield electromagnetic environment, various false parameter information forms different types of deception interference, which seriously affects the detection and tracking of radar parameters such as target distance and speed. In recent years, spoofing jamming has become one of the main ways of radar jamming, seriously affecting the survival status of radar. Traditional radar signal optimization methods cannot resist copy-and-forward interference. Contents of the invention [0003] Based on this, it is necessary to provide a radar signal optimization method, device, computer equipment and storage medium capable of resisting copy-and-transfer interference for the above-mentioned technical problems. [0004] A rad...
