摘要

单元插值位移相位中心天线(DPCA)采用分数阶延迟滤波器来获得良好的地面运动目标指示(GMTI)性能，而传统的DPCA条件无法满足。其GMTI性能严重依赖于所采用的滤波器。本文对元件插值DPCA中的4种分数阶延迟滤波器进行了评估，并提供了选择合适的滤波器以获得最佳GMTI性能的指南(ICCCAS'07)。

Evaluation of Several FIR Fractional Delay Filters in Element-Interpolation DPCA

Element-interpolation DPCA (Displaced Phase Center Antenna) employs a fractional delay filter to get good GMTI(Ground Moving Target Indication) performance while conventional DPCA conditions cannot be met. Its GMTI performance seriously depends on the adopted filter. This paper evaluates 4 fractional delay filters in element-interpolation DPCA, and provides guidelines for choosing an appropriate filter to get best GMTI performance (ICCCAS'07).
