Abstract:
1. A target object detection device for detecting different detection areas by different pulse-shaped signals and synthesizing detected information to detect an area from an antenna position to a given distance, comprising: a transmission module for transmitting at least two or more different pulse-shaped transmission signals at predetermined timings; a reception module for receiving a reflection signal of each of the transmitted pulse-shaped transmission 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 foaming module for forming a detection image based on the reception signals; wherein 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, and 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.
