A multi-DSP signal processing and control system for MST radar

Atmospheric remote sensing by Doppler radar is an increasingly used technique. An MST radar is an instrument that can be used for mesosphere, stratosphere and troposphere remote sensing. This paper describes a signal processing and control system for atmospheric sounding radars, with improved characteristics with respect to formerly used architectures. The authors refer especially to wind profiling as an important and interesting application. The system allows up to 4 receiver signals to be processed at the same time, with 60 range gates and 300 m height resolution. The use of two DSPs working in parallel allows the use of a single PC for real time data processing and system control. Some experimental results are reported.
