Embodiment Construction
[0021] The present invention provides a waveform optimization method for detecting moving targets in a complex environment based on prior knowledge, and the background clutter response h is known c (t) is modeled as a generalized stationary complex Gaussian random process; the additive noise response also obeys the complex Gaussian random distribution; the target moving speed is known. According to the Naiman-Pearson criterion, the frequency domain of the transmitted waveform is designed to achieve the optimal waveform based on the detection rate for a specific moving target. The specific process block diagram is as follows figure 1 Shown.
