The invention provides a sea clutter suppression processing and performance analysis method based on a video signal, and the method comprises the steps: carrying out the high-false-alarm high-detection-probability detection of a preprocessed radar echo, carrying out the inter-frame correlation detection, SIC inter-frame accumulation detection, and traditional CFAR detection multi-channel detection, and carrying out the detection of a high false alarm rate and a high detection probability. And finally, according to the sea clutter region information, carrying out combinational logic judgment on the multi-channel detection result. According to the processing flow, sea clutters can be effectively suppressed through inter-frame accumulation, improvement of the detection performance of inter-frame static or slow targets is facilitated, and the detection performance of moving targets is ensured through multi-channel detection.

The invention provides a radar target track initiation method based on a quantum particle swarm and LGBM. The method comprises the following steps: acquiring and marking original data; feature extraction of the data: establishing an initial feature vector and further extracting target features from space-time dimensions; establishing and training a LightGbm model, and selecting parameters of the model by using grid search and cross validation; optimization of a probability threshold: establishing a function of an objective function about a probability threshold parameter, performing parameter optimization by using a QPSO algorithm, and obtaining the probability threshold when the objective function is converged to a maximum value; and deployment and application of the LightGbm model are carried out. According to the method, on the basis of extracting multi-dimensional features of a target initial track, a LightGbm model for target track false discrimination is established, a probability ...
