摘要

Using an experimental coherent high-resolution X-band radar, we show that micro-Doppler signatures from one or more walking persons can be retrieved off the radar line of sight in a realistic urban environment. The off-sightline objects are illuminated by the radar wave multipath wall reflections. Velocity–time diagrams are created for specific walking targets using the short-time Fourier transform. Two scenarios are studied, with one and two persons, respectively, walking along a closed path.
