摘要 基于一个高频双极化雷达系统,给出了一种利用辅助水平天线抑制Es层干扰的自适应系统。水平极化天线接收的数据与垂直极化天线接收的数据进行相关,自适应的估计出垂直天线接收中的干扰,然后对消掉它们。干扰对消在每个相参积累周期后进行。实际数据对消后的信噪比可以提高到25dB。 Based on a dual-polarization high-frequency wave radar system, an adaptive system using auxiliary horizontal antennas for the suppression of the Es layer interference （ELI） is described. The data received from the horizontally polarized antennas （HPAs） is correlated with the data received from the vertically polarized antennas （VPAs） to estimate and cancel the interference adaptively in the VPAs. Suppressing the interference after each coherent integration time interval, about 25 dB signal-to-interference ratio is obtained with the experimentally derived data.
