Abstract

The present invention discloses a processing system for a precision tracking and instrumentation radar signal, which is composed of a commercial server, two GPU computing cards and two PCIE four-channel optical fiber interface cards on hardware. With the invention, data from an echo simulator, a high-speed acquisition device or an outfield radar can be respectively received, narrowband full rangeand gate echo signals can be respectively processed; A/R information can be generated; automatic closed-loop precision tracking and parameter measurement for a target can be carried out; echo signalswith different waveform parameters and target types under different environments can be processed; the requirements of the spatial target monopulse precision tracking and instrumentation radar for measurement accuracy, real-time capability and software adaptability can be satisfied; and the problems of traditional tracking measurement signal processors such as poor software portability, long development cycle and difficult upgrading are solved.

Description

technical field [0001] The invention belongs to the technical field of precision tracking and measuring radar, and in particular relates to a processing system for precision tracking and measuring radar signals. Background technique [0002] Due to the continuous improvement of the requirements of single-pulse precision tracking measurement radar in terms of parameter measurement accuracy and real-time performance, the processing speed and performance of the signal processor also need to be improved accordingly. Traditional solutions based on FPGA and DSP often lead to difficulties in updating radar systems and function expansion, and have poor portability and flexibility. The heterogeneous processor platform has outstanding advantages in parallel computing, and can reasonably allocate tasks with different computing characteristics to processors with different structural characteristics, thereby greatly improving the overall performance of the processing platform to meet the...
