Abstract
A six-port self-injection-locked (SIL) radar includes an oscillation element, an antenna element, a six-port frequency demodulation element and a signal processing element. Because of a coupler and a phase shifter of the six-port frequency demodulation element, the signal processing element can extract vibration information of subject by using only two demodulated signals output from the six-port frequency demodulation element. As a result, the operation frequency of the six-port SIL radar is not limited by hardware architecture, and the hardware costs and the power consumption are also reduced.
