Abstract

The invention discloses a VPX-platform-based radar signal processing system and an application software design method. The processing system operated in a VPX processor comprises a hybrid communication board and a universal signal processing panel. The hybrid communication board is integrated with a multi-channel AD / DA and a Virtex-7 FPGA processor and is used for frequency-modulation waveform control, signal acquisition and corresponding signal pre-stage pre-processing work, and carrying out radar work time-sequence controlling. The universal signal processing panel integrated with a multi-piece multi-core DSP6678 processing architecture is used for realizing high-performance computing, wherein the high processing capability is realized by a parallel system formed by a plurality of processors. According to the invention, the radar signal processing system with high universality and extensibility is constructed by using a VPX-architecture-based universal ruggedized computer and the high processing capability is realized by the parallel system formed by a plurality of processors. The radar signal processing system has characteristics of small size, firm structure, and good heat radiation performance and thus the radar signal processing is modularized, standardized, and universalized, so that function integration of the system under various radar mode application backgrounds.

Description

technical field [0001] The invention belongs to the technical field of digital signal processing, in particular to a radar signal processing system and application software design method based on a VPX platform. Background technique [0002] Traditional radar signal processing systems generally select the appropriate hardware architecture according to specific task requirements, and customize a dedicated signal processing board to complete the radar signal processing work. Due to the different tasks of signal processing, the designed radar signal processing systems are quite different and not compatible with each other, which affects the generality and scalability of the system. When the application environment, real-time requirements, system scale, and application algorithms of signal processing change, the entire system needs to be redesigned and the design and verification cycle is long, which cannot meet the increasingly complex and diverse application of radar technolog...
