Abstract

Skywave radar exploit the ionospheric medium to illuminate and track targets at long ranges over vast areas. To achieve optimal performance in the dynamic clutter and noise environment cognitive radar techniques are used to advise waveform parameter and coordinate registration for localisation of targets. Here we introduce an experimental high spatial resolution support-radar that remotely senses surface backscatter clutter. A robust algorithm is described for analysis of the Doppler spectra to determine land or sea backscatter origin. The sensed land-sea interfaces can thus be used for direct registration of nearby targets or assimilation into an ionospheric map.
高频雷达航迹配准的高分辨率广域遥感
天波雷达利用电离层介质来照亮和跟踪广大地区的远距离目标。为了在动态杂波和噪声环境下获得最佳性能,采用认知雷达技术来建议波形参数和坐标配准以实现目标定位。本文介绍了一种用于遥感地表后向散射杂波的实验性高空间分辨率支撑雷达。描述了一种鲁棒的多普勒谱分析算法,以确定陆地或海洋的后向散射源。因此,所测得的陆海界面可用于直接登记附近目标或同化成电离层图。
