<p>PROBLEM TO BE SOLVED: To provide an image faithful to the intensity of a target signal, having a sufficient distance resolution in an FM-CM radar device. SOLUTION: An FFT analyzer 111 and an MEM analyzer 112 are used as frequency analyzing means, a range determined to have a target by a comparator 12 is extracted from the output of the FFT analyzer 111 that is faithful to the intensity of a target signal, result of analysis for the range is extracted from the output of the MEM analyzer 112 that has an excellent resolution using a gate circuit 13. By determining that there is a target when a threshold value is exceeded in a comparator 14, a well-resolved target pulse signal is generated, and an image by this is combined with image display based on output of the FFT analyzer 111 on a display 16 to be displayed.</p> |
