PROCEDURE OF COMPLEX PROCESSING RADAR DATA IN STROBE AND SELECTION OF RADAR MARK
The reliability and accuracy information about approaching ships generated by Automatic Radar Plotting Aids (ARPA) determine equipment performance. Selecting target plot in the strobe is basic problem in generating target's data. The procedure is multistage whereas every step requires different methods. The article considers different approaches to forming a strobe and tracking the target while using pulse radar. The following key stages have been distinguished: evaluation of noise level in the strobe, selection of marks for target tracking, tracking of the acquired target andtracking reset. Each stage has been structurally evaluated for the functionality purposes. The most problematic issues related to the limited sampling, sampling frequence and noise level of the radar signals have been singled out. There is the possibility the noise reduction through digital processing and signal anaylsis for AND condition, i.e. to confirm the signal delivery at previous antenna scanning. Direct increase of skips in passes can reduce noise effectively,however it may result in the loss of a fast-moving small size target which is especially dangerous on small-scale range, when in between the reviews an object can pass a sector equal to the width of the antenna pattern. The authors provide recommendations as per formalizing the procedure of target selection in the strobe. The efficiency of K-band radar at capturing and tracking of the targets is has been esitmated. The paper highlights the specificity of the problem solution for coastal and shipborne navigational radars. The approach which consists in separatiing computing resources between hardware (radar processor, graphics card) and digital indicator has been highlighted. An important aspect in solving the problem is fusing the data from different sources, including automatic identification systems and prospects of artificial intelligence application. The general algorithm for solving the problem has been provided.
