<p><P>PROBLEM TO BE SOLVED: To perform signal processing capable of detecting a target, even when SNR (Signal-to-Noise Ration) after coherent integration is extremely low. <P>SOLUTION: This target detection device is equipped with a receiving means 1 for receiving a reflected pulse from the target, and performing A/D conversion of reception data in each pulse hit; a signal reproduction means 2 for adding a noise series to a receiving video comprising a data series of the reception data after A/D conversion, and reproducing a signal; a coherent integration means 3 for performing FFT processing in the pulse hit direction to the receiving video after signal reproduction; and a threshold means 6 for comparing an integration result by the coherent integration means 3 with a prescribed threshold, and determining as target detection when exceeding the threshold. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
