PURPOSE:To enable the tracking of a target stably regardless of any jamming wave received from a target by performing an angle tracking of the same target with two radars to calculate the distance of the target from differences in angle. CONSTITUTION:First and second radars 1 and 8 are used to track the same target and distance information of the target to be tracked from the radars 1 and 8 is inputted into first and second distance input buffer circuits 3 and 10 while angle information is inputted into an angle input buffer circuits 4 and 9. Output signals of the angle input buffer circuits 4 and 9 are inputted into a target distance calculator 5 to calculate target distance information Ra1 and Ra2. These pieces of information are sent to target position estimating devices 7 and 13 through switches 6 and 12 changeable with the outputs of jamming wave detectors 2 and 9. The estimating devices 7 and 13 estimate the target position from the information Ra1 and Ra2 and output signals of the angle input buffer circuits 4 and 9. |
