A Novel Partial Coherent Detection Algorithm for Over-The-Horizon Radar

This paper addresses the partial coherent target detection problem for over-the-horizon (OTH) radar in Gaussian noise and clutter environment. The Gaussian distribution is adopted to model the noise and clutter based on the low range resolution characteristic of OTH radar. The novel detectors are proposed in the presence of partial coherent signals. To be more concrete, by using the likelihood ratio test (LRT), we develop the partial coherent detector, coherent detector, and noncoherent detector. The performance of the proposed detectors is evaluated and compared by using the simulated partial coherent signals data. The numerical results show that the partial coherent detector performs better than the coherent detector and noncoherent detector.
