<p>PURPOSE:To reduce the occurrence of delay time caused by PDI processing in a signal processor for searching and tracking radar equipment which performs the PDI processing. CONSTITUTION:In the title processor for searching and tracking radar equipment, an output signal level detection circuit 2 which detects the level of the output signal of an AGC circuit 1 and a circuit 3 which decides the number of processing times from the output signal of the circuit 2 are provided. When received signals are small, the S/N ratio of the signals is improved by increasing the number of processing times and, when the signals are large, a stable S/N ratio is obtained at any time by reducing the occurrence of delay time caused by the PDI processing and preventing the deterioration of searching and tracking accuracy by decreasing the number of processing times.</p> |
