Abstract: In this paper,a signal processing platform for radar measurement system including 4 ADSP-TS101 and based on ComactPCI bus is presented,which inner structure is analyzed in detail.This platform has many positive characteristics such as strong computational capability,broad IO bandwidth,various communication methods,topology visibility,and good scalability.This system distributes echo signal processing over parallel DSP in high speed.This system also can simultaneously save echo data of millimeter-wave radar while doing signal processing,thus provides important measurement data for radar target signature analysis.
