摘要: A moving obstacle detection system for an automotive vehicle utilizing a doppler effect of the transmitted wave against which runs in front such as another vehicle. The generally comprises: (a) radar unit operates so to produce signal when is halted; (b) detecting means detects changing phase produced from signal; (c) discriminating discriminates departure area and intersection or pedestrian traverse on basis frequency rate amplitude level detected (d) alarm produces predetermined form only case straightly approaches departed goes across vehicle, separately each other.
