<p>PROBLEM TO BE SOLVED: To provide a radar system capable of increasing the coherent integral gain of a reflection wave signal reflected by a target using a simple configuration.SOLUTION: A radar transmission section converts a transmission signal into a high-frequency radar transmission signal to transmit the same from a transmission antenna. At least one radar reception section receives a reflection wave signal which is the radar transmission signal reflected by the target using a reception antenna. The correlation calculation section calculates correlation value between the reception signal and the transmission signal for each transmission period of the radar transmission signal. A Doppler frequency detection unit performs a coherent integration on (Np×Nc: Np, Nc: integers equal to or more than one) correlation values using a correction amount of a Doppler phase rotation corresponding to different plural Doppler frequencies.</p> |
