Embodiment Construction
[0095] The present invention will be further elaborated below in conjunction with embodiment.
[0096] The present invention provides a sea clutter suppression method based on the radar signal space-time decorrelation model, which can better utilize the space-time two-dimensional degrees of freedom of the multi-channel radar echo data of the moving platform to improve the sea clutter suppression ability, and Based on the sea clutter space-time decorrelation model, the estimation accuracy of the clutter plus noise covariance matrix is improved in small samples to solve the problems of large output loss of slow moving targets and unrobust sea clutter suppression performance of the existing sea clutter suppression technology question.
[0097] Sea clutter suppression methods such as figure 1 As shown, it specifically includes the following steps:
[0098] Step 1. The radar is set with N channels, each channel generates K pulses, and each pulse is set with L range gates; the r...
