FMCW Radar sensor is commonly used for an automobile collision avoidance system for rider’s safe. Systems using FMCW radar, however, would be one of expensive solutions for just simple rear obstacle detection purpose due to its high cost. In this letter, a short range rear obstacle detector using novel 24㎓ AM radar sensor is presented. It can be implemented at significantly lower cost than FMCW radar for practical commercialization. The proposed AM radar sensor module is fabricated in a single aluminum housing to reduce the overall size while using single power supply voltage of 12V with 1200㎃ current for automotive applications. The measured detection range is up to 210㎝ with 10㎝ of distance resolution, which is suitable for a parking assistance system for automobiles.
