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 present application relates to a radar anti-intermittent sampling and forwarding interference method, device and radar equipment. The method includes: constructing a plurality of subcarriers based on orthogonal frequency division multiplexing technology, and phase encoding corresponding to the subcarriers, constructing a multi-carrier phase encoding radar signal according to the subcarriers and phase encoding, and according to a pre-generated chaotic time sequence, The time domain and frequency domain of the multi-carrier phase-encoded radar signal are encoded to obtain the radar signal to be transmitted, and the radar signal to be transmitted is transmitted to combat intermittent sampling and forwarding interference. The method can solve the problem of intermittent sampling and forwarding interference.

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...
