Abstract
Millimeter-wave radar for collision avoidance, takeoff and landing in challenging environments requires high resolution imaging. Mechanically scanned radars are expensive and limited by a short dwell time on target. An electronically scanned array is an attractive solution, but requires large numbers of transceivers. MIMO permits thinning of the array without compromising image quality. Each transmitter element is encoded with a unique sequence. A problem is Doppler, due to target and platform motion. This restricts the selection of sequences. We present suitable sequences and a signal processing scheme.
