Subsection Pulse Compression Processing Platform of Broadband Radar Based on Pipelined DSP
abstract：The method of real-time realizing of the subsection pulse compression of radar is analyzed via frequency-domain algorithm.A parallel algorithm based on pipelined DSP is discussed,and the expressions of the whole time of the pulse compression and the number of the pipelined DSP are proposed.Within the given time,the performance of the subsection length is discussed and a high performance subsection pulse compression processing platform which uses four ADSP-TS101s as key components is designed,and corresponding experiment result is obtained.
