Range resolution improvement for low-cost FMCW self-mixing radar

The principals of range resolution improvement the self-mixing (autodyne) surveillance radar for object detection on distances from ones to hundred meters are considered in this paper. The description of the flow chart, main parameters and results of test bed model examination are given. Application of the self-mixing regime with internal detection allowed to make the construction easier dimensions smaller to increase reliability of the transmitter and the sensor in whole.
