PROBLEM TO BE SOLVED: To make it possible to improve an S/N ratio by effectively using other received spectra in an HPRF radio wave active type guidance system mounted radar device that conventionally inhibits noise and ensure the S/N ratio by extracting only one of a plurality of received spectra subjected to frequency keying by as much as a Doppler frequency when radiating a pulse-modulated transmit wave to a target and performing a receiving process on a reflected wave.SOLUTION: In a radar device, a receiving system including a plurality of narrow-band filters receives a plurality of spectra, and received spectra including a plurality of target signals are corrected according to a distance, a Doppler frequency, and PRI specifications and subjected to coherent integral, thereby improving an S/N ratio. |
