Because the data collected by radar is too dense, in order to improve the operation speed and data accuracy, the idea of limited memory real-time sequential algorithm [real-time sequential algorithm of measurement data processing] is used to process the measurement data. Considering that the echo trace of radar is four-dimensional, it is more likely that the points which are closer in time are adjacent in space. Therefore, in data association analysis, a sliding window is set on the time axis, and only the data in the window is analyzed each time. Data2.txt provides 2650 sets of data. Considering the calculation time, the window size is set to 100 units, and each unit can store 1 set of data. The window slides in a specific direction along the timeline, each time
