A method is described which overcomes the problems of multipath propagation and range ambiguity that is suffered by the single-frequency continuous-wave microwave-imaging system described in part I. This technique is essentially a variation of chrip radar techniques, which have been adapted to time delay and attenuation measurements through a target. The feasibility of discriminating between paths whose differential time delay is on the order of 100 ps is demonstrated. Further, the need for small physical aperture in the transmitting and receiving antennas is demonstrated.
本文描述了一种方法，该方法克服了第一部分所述单频连续波微波成像系统所面临的多径传播和距离模糊问题。该技术本质上是一种线性调频雷达技术的变体，已被应用于通过目标进行时间延迟和衰减测量。文中证明了区分差分时间延迟在100皮秒量级的路径的可行性。此外，还证明了发射和接收天线需要小物理孔径。
