Embodiment Construction

[0031] 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.

[0032] The radar anti-intermittent sampling forwarding interference method provided by this application can be applied to such as figure 1 shown in the application environment. Among them, the radar device 102 can transmit radio waves, and after the radio waves reach the scatterer target 104, they reflect the return radio waves, and the radar device 102 receives the return radio waves to locate the scatterer target 104. When there is intermittent sampling interference, the jammer 106 The radio wave is intermittently sampled, so as to form a coherent jamming machine string...

Abstract

The invention relates to a radar intermittent sampling and forwarding interference resistance method and device and radar equipment. The method comprises the steps that based on an orthogonal frequency division multiplexing technology, multiple subcarriers and phase codes corresponding to the subcarriers are constructed; according to the subcarriers and the phase codes, a multi-carrier phase coderadar signal is constructed; according to a chaotic time sequence generated in advance, a time domain and a frequency domain of the multi-carrier phase code radar signal are encoded to obtain a to-be-transmitted radar signal; and the to-be-transmitted radar signal is transmitted to resist intermittent sampling and forwarding interference. By the adoption of the method, the problem of intermittentsampling and forwarding interference can be solved.

Description

technical field [0001] The present application relates to the technical field of radar information processing, and in particular to a radar anti-intermittent sampling and forwarding interference method, device, radar equipment and storage medium. Background technique [0002] In the context of information warfare, electronic jamming patterns are flexible and changeable, especially the development of digital radio frequency memory technology, which poses severe challenges to radar. Intermittent sampling and forwarding jamming is a new broadband radar coherent jamming method, which uses sampling and forwarding alternately, and has a good jamming effect on radar pulse compression signals. At present, the literature on the identification and suppression of this interference is relatively limited, mainly focusing on the research in the fields of waveform design, time-frequency analysis, and spectral feature extraction. Although waveform agility technology has good performance ag...
