| Abstract: | High-frequency skywave over-the-horizon radar (OTHR) can provide a wide coverage over the horizon by means of the refraction within the ionosphere. However due to the complex propagation conditions of electromagnetic wave in HF band, many disadvantageous effects, such as phase path contamination and multimode propagation, will cause the target submerged by the neighboring spread clutter. In this paper, the spread effect of identical clutter backscattered from the adjacent dwell illumination region (DIR) has been discussed. On the basis of the existing matched field processing (MFP) method developed for this problem, the multiple-dimension cross-relation method using the multiple channel signals has been proposed and used to the temporal data directly. Experimental simulations are given to demonstrate that the improved method is effective to suppress the spread clutter. | ||
