PURPOSE:To enable the titled device to obtain the stable automatic tracking of a moving target by storing preliminarily clutter information around estimated position of the moving target, comparing a received signal with the clutter signal to remove the clutter signal. CONSTITUTION:A signal outputted from a signal detecting section 4 is sent to a correlation processing section 7 and a clutter information processing section 5. The correlation processing section 7 compares data of the position of the moving target estimated by an estimation calculating section 8, and data such as a position of generation of clutter around the estimated position, amplitude, width, etc. outputted from a storing section 6, with a moving target signal and a clutter signal outputted from the signal detecting section 4, and takes out an actual moving target signal. The clutter information processing section 5 calculates an average value, dispersion, etc. for plural times of data such as the position of generation of output signal, amplitude, width etc. when an antenna beam scans the surrounding of plural positions estimated by the estimation calculating section 8, and inputs the result to a storing section 6. |
