Description

technical field [0001] The invention relates to a radar signal processing method, in particular to a wind profile radar signal processing method. Background technique [0002] Wind Profiling Radar (WPR) is an all-weather atmospheric remote sensing detection device that continuously detects physical quantities such as atmospheric wind field by detecting the reflection and scattering of electromagnetic waves by atmospheric turbulence. It has high real-time and precision of wind measurement. It is one of the key equipment for small and medium-scale atmospheric detection, and has been rapidly developed and applied in my country. [0003] The original wind profile radar signal processing method uses a dedicated imported signal processor. The imported signal processor includes: AD conversion components, DSP signal processing components, and the hardware is complex and expensive. Due to limited hardware resources, it is limited in algorithm expansion, calculation accuracy, data sto...
