Abstract

PURPOSE:To improve the performance for separation of crossing of plural targets, by using signal intensity besides position information to track targets correlatively. CONSTITUTION:A range R1, an azimuth theta1, and a signal intensity S1 detected by a radar receiver are stored temporarily in a buffer 1. Target data R1, theta1, and S1 stored in the buffer 1 are compared with tracking forecasted data Rp, thetap, and Sp, which are stored in a buffer 6, by correlators 2, 3, and 4 concerning the range, the azimuth, and the signal intensity, respectively; and if the input difference is within an allowable range, data R1, theta1, and S1 stored in the buffer 1 are transferred to a format register 5. The forecasting operation based on correlated target data R1, theta1, and S1 is performed in a forecasting operator 8, and operation results Rp, thetap, and Sp are transferred to a tracking information memory 7 to update forecasted data.
