Standing waves observed using near-field radar measurements.

    I just began to experiment with a low power (5 dB m) continuous and pulsed radar. I am hoping to use the radar to measure the radar cross section (RCS) of different materials. This experiment is intended to compare the RCS with surface emissivity measurements obtained radiometrically. However, I observed wave interference in the measurements similar to the case of a slotted line that I am trying to eliminate. I tried using separate antennas spaced apart as well a single antenna using a circulator for separation and got the same interference pattern. Any suggestions or explanations would be appreciated.

    Use a VNA in time domain mode to gate out the reflections.

    Thanks, I agree with you. I was just hoping to avoid the need for digital processing in the time domain.
