<p>PURPOSE:To enable capacity for each target to be improved by constituting a title item with a two-dimensional distribution forming part, a threshold processing part, a pattern recognition part, and a target candidate distribution forming part. CONSTITUTION:Signal received by a reception antenna 51 is amplified by an amplification circuit 52, is converted into digital signal by an A/D conversion circuit 53, and a two-dimensional distribution information is formed by a two-dimensional distribution forming part 54. A threshold processing part 56 enters an output from the two-dimensional distribution forming part 54 and a target position information from an inertial device 55, performs threshold processing, and then outputs the result as a binary data. A pattern recognition part 57 receives the binary data from the threshold processing part 56, extracts a clutter pattern of angle and that of distance, and then outputs them to a target candidate distribution forming part 58. The target candidate distribution forming part 58 excludes the clutter pattern of angle and that of angle from the binary data, and then forms the target candidate distribution.</p> |
