Design and realization of airborne PD tracking radar signal processor

The features of a paracontinual wave three channels radar receiver were analysed and an advanced scheme of digital signal processing system was proposed. Some advanced techniques were applied, including intermediate frequency sampling technique, very high speed DSP and its parallel architecture. To realize the design, the limit of some existing intermediate frequency sampling methods was analyzed, and a new intermediate frequency sampling filter was proposed. The hardware ADSP21060 was described and the advanced 32-bit float point DSP and its parallel architecture were used in the system.
