| Abstract: | The paper describes a new method for decreasing the fixed error in a conventional FM-CW radar.This is the method of the double frequency mixing modulation.Since this method requires merely narrow frequency band,the configuration of the radar is simple and compact,the paper analyses the error of the FM-rabar,describes the principle of double frequency mixing modulation,and the example of the practical application of the radar. |
