基于大型微波暗室小目标 RCS 测量与分析

摘要

A broadband swept frequency radar cross section (RCS) measurement system based on vector network analyzer is established. Error analysis and verification confirm that this measurement system can be used in large microwave anechoic chamber to measure RCS of UAVs as well as RCSs of other small sized targets.%基于矢量网络分析仪构建了宽带扫频 RCS 测试系统，通过误差分析与验证，该系统在大型微波暗室中满足无人机 RCS 测试要求，可以完成小目标 RCS 的测量。
