Moving DS-OTHR array reconstruction algorithm based on interpolation

Distributed shipborne over the horizon radar (DS-OTHR) is a new radar detection system that becomes a new research direction of shipborne OTHR. Array reconstruction and signal reconstruction are the key techniques in the radar system. Reasonable reconstruction for moving distributed radar receiving subarrays can realize accurate measurement of target. In this letter, we propose an interpolation approach for time-varying radar system where uniform linear subarrays (ULSA) are on different baselines, and apply the approach to different conditions.
