Realization Techniques Of Target Detection Based On T~n-R External Illumination Radar System

This dissertation firstly introduces the structure and properties of digital signal processing chip ADSP-TS101 which is applied to the passive radar signal processing subsystem based on multiple illuminators and signal receiver, and describes a general-use parallel processing system constructed with several pieces of ADSP-TS101 chip. Then, a structure of the high-speed real-time signal processing subsystem is given which is based on general-use signal processing board with ADSP-TS101 as the chief chip. Secondly, the basic principles of digital down conversion, adaptive clutter cancellation and pulse compression in the passive radar system are introduced separately. Finally, the design processes and implementations of software algorithms of each module are explained especially according to the general-use hardware platform. And the realization method of distributing multi-channels data vastly and stably is discussed using the FPDP (Front Panel Data Port) bus, which solves the tough problem of data transmitting in the system and pledges the real-time performance in processing.
