摘要：
A novel radar is proposed and verified based on a two-element time-modulated array. The distance of the object is estimated from the time delay between the source signal and the return one, while the direction is calculated by analyzing the spectrum of the return signal after the time modulation. The proposed radar needs no rotary machinery or electronic scanning system to detect the direction of the object, and it can deal with multiple objects from different directions simultaneously, if their distance differences are larger than the range resolution. Numeric simulations are provided to verify the proposed method.
