Description

technical field [0001] The invention relates to a method for analyzing electromagnetic interference of a moving target on a random rough sea surface. Background technique [0002] At present, the prediction and analysis of the electromagnetic environment of complex moving targets under random rough background is often obtained by simply superimposing the electromagnetic environment of each sub-target. Due to the random disturbance of the environment, the relative position of each target is uncertain; due to the influence of space-time complexity, the composition of the target also shows uncertainty at different times. In this realistic background, the above-mentioned traditional analysis method There must be large errors. [0003] At present, the research on electromagnetic interference is mainly focused on the equipment level or system level. The research on electromagnetic interference (EMI) of complex targets usually adopts a four-level screening method, namely, sub-ampl...
