一种非相干散射雷达发射码优化方法
Transmission code optimization method for incoherent scatter radar
摘要：
当使用滞后分布的统计反演来确定非相干散射目标时，估计目标的后验方差可以用于确定某组传输码执行得有多好。本文提出了一种适用于二相、多相和调幅等不同调制方式的非相干散射雷达传输码优化搜索方法。我们发现，幅度和相位调制的组合提供了更好的性能比传统的二进制相位编码，在某些情况下，提供更好的精度比交替码。
英文摘要：
When statistical inversion of a lag profile is used to determine an incoherent scatter target, the posterior variance of the estimated target can be used to determine how well a certain set of transmission codes perform. In this work we present an incoherent scatter radar transmission code optimization search method suitable for different modulation types, including binary phase, polyphase and amplitude modulation. We find that the combination of amplitude and phase modulation provides better performance than traditional binary phase coding, in some cases giving better accuracy than alternating codes.
