[Brief explanation of the drawing]

FIG. 1 is a block diagram showing a signal detection device according to one embodiment of this invention, FIG. 2 is a block diagram showing another embodiment of this invention, and FIG. 3 is a block diagram showing a conventional signal detection device. . In the figure, 1 is an input terminal, 2 is a pulse accumulation buffer, 3 is a frequency output line, 4 is an arrival pulse time output line, 5 is a frequency frequency distribution creation circuit, 6 is a final time creation circuit for each frequency frequency distribution, and 7 is a frequency A frequency distribution memory, 8 a target determination circuit, and 9 a simultaneous input determination circuit. In addition, in the figures, the same reference numerals indicate the same or equivalent parts.

Claims (1)

[Scope of utility model registration request] A pulse signal detection device arriving from a radio wave emission source such as a radar includes an accumulation buffer that accumulates incoming pulse data, and a frequency frequency distribution creation circuit that counts the number of incoming pulses for each specified frequency width and stores this count value. , a final time memory circuit for each frequency frequency distribution that stores the final time of the arriving pulse for each frequency frequency distribution, a frequency distribution memory for each frequency that stores the count value and the final time, and a memory circuit for each frequency frequency distribution that stores the final time of the arriving pulse for each frequency frequency distribution, and a memory circuit for each frequency frequency distribution that stores the final time of the arriving pulse for each frequency distribution. A signal detection device comprising: a target determination circuit that determines whether or not a target is detected.
