Abstract

PURPOSE:To perform sepn. and identification of the case in which the positions of plural aircrafts are in proximity to each other by correlating the positions of a target detected with a radar and speed information. CONSTITUTION:The target position information by the past distance RT and bearing thetaT detected with a radar and the speed information by the frequency deviation are correlated with the forecast distance, bearing and speed information RP, thetaP, VP through a memory 7 and a buffer memory 6 via a tracking target data forecasting part 8 in accordance with these sets of information with correlators 2-4. When the differences between these sets of the information are less and the correlations are obtained, the current input target information is fed via a controller 5 to the part 8. When no correlations are obtained, the buffer 6 is controlled by the controller 5 and the another forecast information is transferred to the correlators 2-4 in order to obtain the correlations, whereby the sepn. and identification of the case in which the positions of plural aircrafts are in proximity to each other are accomplished surely.
