Abstract

The invention discloses a radar clutter simulation method and electronic equipment, and the method comprises the steps: collecting original clutter data, carrying out the preprocessing, and obtaining and splitting a distance unit of the preprocessed clutter data; constructing an info-WaveGAN training model comprising a generator, a discriminator and a Q network; taking each split distance unit as a training sample to be input into an info-WaveGAN training model, and carrying out model training through the generator, the discriminator and the Q network in sequence; and creating a loss function, and performing optimization processing on parameters of the training model by circularly executing a loss function minimization operation to obtain optimized clutter data. According to the method, the model fitting capability is improved to generate more vivid clutters, the distribution type of the input radar clutters is ignored, the method can be applied to generation of radar clutters of any distribution type, and the universality of the method is improved.

Description

technical field

[0001] The invention relates to the field of radar signal processing, in particular to a radar clutter simulation method and electronic equipment. Background technique

[0002] Radar echo signals include target echo, clutter echo, and noise, etc. Ground objects, clouds, rain, sea waves, chaff, etc. will reflect electromagnetic waves to form clutter, covering or interfering with the detection of radar targets. In order to deeply study the influence of clutter on radar detection performance, radar designers need to analyze and model radar clutter characteristics in order to formulate reasonable radar design schemes, select radar parameters, and take various anti-clutter measures.

[0003] The test environment of the field test is unstable, subject to restrictions and influences, which will slow down the development progress, and each test will consume a lot of resources. Using realistic simulated clutter as the input of radar design has the advantages of flexi...
