With the increase of radar coverage and improve the accuracy of radar,radar data increases,the existing track condensation method has been difficult to meet the demand of real-time radar data processing.In this paper,through the research of radar target range,azimuth,relative velocity and size of shape measurement.Analysis of the target in the range expansion,narrow-band radar and wideband radar target expansion caused by expansion and different target in azimuth,the multipath effect of the binary sliding window and moving target detection of the target in the extension direction and radar echo in azimuth dimension caused by target expansion.Through the measurement of radar video data from the azimuth and distance dimension expansion and radar video data in terms of target echo amplitude,normal dim target and sea clutter are analyzed.In the face of radar data processing huge amount of data,this paper analyzes several existing algorithms in performance,which is the traditional plots' agglomerating method,extraction method of fast clustering method,single dimensional distance calculation based on star centroid.The traditional plots' agglomerating method is the most widely used in practical engineering,but in the data processing to the data unit to traverse all at least two times.Can not satisfy the real-time processing requirement of radar video data.These methods have their own advantages in data processing,but still can not meet the requirements of real-time data processing.In this paper,on the basis of previous studies,proposes a boundary detection method of radar target based on video data,the data processing efficiency is improved by more than ten times.At the same time,in the process of object boundary detection in this paper puts forward a new method for quick detection of boundary.Radar video data in different environment requires different treatment on the target.Through the actual radar video data acquisition,this paper verified the feasibility of detection method of target boundary in radar data processing,and compared with other algorithms,it is concluded that the method is the best.This paper first introduces the simulation target detection algorithm in MATLAB on the boundary and in the actual project application,followed by that in the three block of data processing board for each CPU function.Then the data was verified on the object boundary simulation method to generate radar video,prove that the method is efficient and strong cohesion.Finally,in the actual radar video data in the trial run of the algorithm,prove that in a large number of the original input video data,object boundary detection algorithm can satisfy the real-time requirements of radar data processing.
