Disclosed is a system and method for a hybrid radar system that integrates frequency-modulated continuous wave (FMCW) mode and interferometry mode. The radar works as a time division system that continuously switches between the FMCW mode and interferometry mode. The FMCW mode is responsible for absolute range detection and the interferometry mode takes cares of the weak physiological movement monitoring. The respective accuracies in range detection and displacement measurement complements the advantages of the two radar modes, providing versatile performance. By steering the antenna beam, the proposed radar system becomes an ideal solution for indoor health care, human localization, and human-computer interaction. Objects or human targets with or without stationary clutters can be precisely located. At the same time, the targets' vital signs and gestures can be monitored. |

1. A method for object localization and monitoring, comprising the steps of:
transmitting, via a computing device, a first signal comprising frequency modulated continuous wave (FMCW) signal; transmitting, via the computing device and concurrent with the transmission of said first signal, a second signal, said second signal comprising a single-tone interferometry signal; receiving, via the computing device, a third signal comprising an FMCW signal; receiving, via the computing device, a fourth signal comprising a single-tone interferometry signal; determining, via the computing device, signal information associated with said received third signal and said received fourth signal; calculating, via the computing device, range and displacement information respective to the computing device based on said signal information; and visibly displaying, on a display associated with said computing device, range, displacement and gesture recognition based on the calculated range and displacement information. |
