PURPOSE:To make operation easy, by removing the output of a slicer circuit from the output of a buffer circuit and removing automatically and three-dimensionally a stationary target. CONSTITUTION:The received signal (a), elevation angle signal (b) and azimuth signal (c) from the sensor part of a three-dimensional radar equipment are inputted to a buffer circuit 1 and are synthesized to a radar input signal (d) in the circuit 1. The signal (d) is inputted to a detection circuit 2 for a stationary target, which accumulates the signal by as much as for N scanning. The result of the accumulation for the N scan in the circuit 2 is inputted to a slicer circuit 3 and if there is the accumulated result of an M scan or above (M<=N) in the N scan, the result passes the circuit 3. A removal circuit 4 for the stationary target cuts the radar input signal (d) in the region discriminated to be the stationary target and removes the stationary target automatically and three-dimensionally. |
