Abstract

Continuous-wave Doppler radar has been proposed for decades and widely used both in military detection and for civil use, to capture or recognize the motion of objects. Conventionally, continuous-wave Doppler radar is vulnerable in locating the absolute trajectory of the object. In this paper, we use I/Q modulation to receive the echo of hand. A real-time adaptive algorithm is proposed to determine the center of a series of phasor constellation. We also preset three antennas in a line to receive the echo containing Doppler information. Thus, a numerical solution of the trajectory of single object has been proposed, which makes it possible to track objects via continuous wave Doppler radar.
