This disclosure provides a target object detection device for detecting different areas by different pulse-shaped signals detecting an area from an antenna position to a given distance. The device includes a transmission module for transmitting different pulse-shaped transmission signals at predetermined timings, a reception module for receiving their reflection signals to generate a reception signal, a saturation detection module for comparing a level of each of the reception signals with a predetermined threshold to detect saturation of the reception signal, and an image forming module for forming a detection image based on the reception signals. The transmission module generates an alternative pulse-shaped signal that is different from the transmitted pulse-shaped transmission signal when the saturation detection module detects the saturation of the reception signal. The image forming module replaces the saturated reception signal with a reception signal obtained by using the alternative pulse-shaped signal to form the detection image. |
