摘要

针对一种基于雷达的地面真速度测量系统，提出了一种基于插值的精度改进方法。该系统基于两个雷达接收信号的互相关。彻底介绍了插补的理论基础，并确定了一般情况下和特定硬件的限制。给出了包括插值在内的测量结果，并与之前的实现进行了比较。

Theoretical Limits and Interpolation based Improvements of a Correlation Based True-Speed-Over-Ground Estimation

For a radar based True-Speed-Over-Ground measurement system an interpolation based precision improvement is presented. The system is based on the cross-correlation of two radar receive signals. The theoretical basics of the interpolation are thoroughly introduced and its limits are determined for the general case and for a specific hardware. Measurement results including the interpolation are presented and compared to the former implementation.
