A Novel Algorithm of Velocity Ambiguity Resolution for Wind Profiling Radar

Wind Profiling Radar can be used to detect the distribution of atmospheric three-dimensional wind, the quality of velocity information affects its performance directly. Compares to other weather radar, wind profiling radar's velocity ambiguity is particularly prominent when used to detect signal. Multiple PRF (pulse repeat frequency) is often used in radar system in order to solve the ambiguity problem. In this way, radar system has a variety of solutions for ambiguity algorithm in signal processing. In this paper, Doppler frequency series (DFS) algorithm can recover target's true velocity from the coupling velocity estimating directly. Simulation results proved the effectiveness of the method, and show us the DFS algorithm for speed estimation performance. Finally, optimization of one-dimensional set of algorithms - compare screening algorithm and DFS algorithm to ambiguity-resolving, given the speed estimated in the DFS algorithm superiority.
