摘要
提出将对称三角线性调频连续波雷达应用于风速探测中,首先分析了对称三角线性调频连续波雷达信号波形,阐述了雷达测距测速原理,针对单个散射点和多个散射点的情况进行了仿真测试。结果表明能够从对称三角线性调频连续波雷达回波信号中获取风速信息,其探测范围为3 km,测速精度为0.1 m/s,具有较高的实用价值和广阔的应用前景。
In this paper, the symmetric triangular linear frequency modulated continuous wave radar was used in wind speed detection. First of all, the waveform of the symmetric triangular linear frequency modulated continuous wave radar was analyzed. And then the theory of distance measurement and velocity measurement was illustrated. As for a single scattering point and multiple scattering points, we have executed simulation. The results show that wind velocity can be derived from STLFMCW radar echo sig- nal. Its detection range is 3 km and velocity Drecision is 0.1 m/s. which has high practical value and broad application DrosDects.
