Efficiency of Air Target Motion Path Detecting in Case of Radar Data Secondary Processing

The article considers statistical descriptions of time interval estimation for air target motion trajectory au-tomatic detection in radar information secondary processing. Analytical expressions for confidential proba-bilities of the air target motion trajectory automatic detection are obtained. It is supposed that the target loca-tion mark appearance is invariable within the whole observation time. The confidential probability dependences are analyzed from the signal noise ratio for the received signals with random amplitudes and elementary phases. It is shown that the target motion trajectory determination probability increases with the increase of signal noise ratio and decrease of radar observation period number
