| Abstract: |
| This paper introduces a low cost millimeter-wave(MMW) active phased array radar,
which can perform two-dimensional electronic beam scanning(phase controlled in
azimuth while multi-beam ports switched in elevation).This radar is mainly compo
sed of Rotman lens stack,multi-port T/R modules, and high-powered digital signal
processor.Test result shows the radar can realize moving target detecting and t
racking,squint-looking FM-stepped SAR and DBS(Doppler Beam Sharpening) imaging. |
