Popis:	For automobile safety, supplemental equipment such as seat belts and air bags is used. These devices are activated after an accident. In contrast, from the point of view of accident prevention, automotive radar has been developed for collision avoidance. Presently, typical radars are the frequency-modulated type and the pulse-modulated type. It is known that measurement of an object over short range is difficult with these types of radar. Here, we propose a method of realization for radar using a standing wave that can measure a moving target within 2 m at a speed of 0 km/h to 100 km/h in simulations, within the specification of low-power radio equipment to detect moving objects at 24 GHz with a narrow bandwidth of 76 MHz. This radar is not subject to the problems of FMCW radar such as leakage of the transmitted signal and false targets due to nonlinearity of the mixer. © 2006 Wiley Periodicals, Inc.
