Design of test software for Over-The-Horizon Radar system

Due to the relatively coarse resolution in range and azimuth, low detection probability, various clutters or interferences, and time-varying ionospheric propagation channel, the measurements of targets collected from Over-The-Horizon Radar(OTHR) has much uncertainty. Furthermore, ambiguity on target returns derived from the ionospheric multimode propagation effect makes data association and tracking more difficult. In this paper, according to the real requirements of data processing subsystem, a test software package has been discussed and developed for the design on data processing software. It provides an assistant platform for testing, debugging, and verifying some key techniques, such as data pre-processing, adaptive association and tracking, propagation mode identification, and multi-path cancellation.
