Abstract:

A universal highly reliable plot processing hardware platform is developed for interaction between track and plot and realizing double redundancy of radar processing hardware with multi-form high-speed interface and powerful processing capability.It can process four-channel radar plot data simultaneously based on the main component of DSP+FPGA,and can fully satisfy multi-channel data exchange by using standard CPCI bus and six pairs of high-speed channel of 5 Gbit·s-1 data transfer rate as main communication interface.A type of double redundancy radar is taken as an example to describe the engineering realization of plot processing on the platform.It is shown that this algorithm is of practical significance in plot processing,interaction between the track and plot,and filtering of plots between frames.
