As the technological advances, it is possible to perform wide bandwidth signal processing for high range resolution and target identification in the modern radar systems. In order to prevent the deleterious effects of dispersion for wideband signals, a wideband signal can be synthesized by coherently combining the individual narrow band components, meanwhile, clutter mitigation, estimation and discrimination...
In this paper, based on a highly deterministic multipath signal model, we derives 4-rays echo signal formula in multipath. Use MTD to detect the low-angle moving target, but its performance is limited by the multipath propagation factor. Frequency diversity method can resist the multipath fading. Simultaneous detecting in multiple diversity channels can improve the low-angle detecting performance...
