<p>PROBLEM TO BE SOLVED: To improve accuracy by generating predetermined characteristic data on the basis of first characteristic data separated for every pulse modulation signal according to an envelope detection signal of an input signal and second characteristic data from a pulse waveform. SOLUTION: A radar signal recognizer 1A is provided with a first characteristic detection unit D1, a second characteristic detection unit D2, a pulse separation unit 15, a pulse train analysis unit 16, for example. The characteristic detection unit D1 carries out envelope detection of an input signal so as to generate a video signal, and on the basis of the video signal, detects a pulse amplitude, a pulse width, a pulse input time, and the like so as to output them with a pulse frequency and an azimuth signal. The pulse separation unit 15 separates these signals according to recognition targets. The character detection unit D2 stores waveform data provided by processing an input signal into a memory 23, and on the basis of the data, detects a pulse internal information or a pulse edge information and the like. The pulse train analysis unit 16 finds statistics data from the data of the pulse separation unit 15 so as to take matching with the data from the characteristic detection unit D2.</p> |
