Design of Echo Information Processing Platform Based on VPX Bus

The echo information processing platform is an important part of the phased array radar system. With the increasing demands of the airborne phased array radar mission on bus transmission bandwidth, computational processing speed, system response time, and data processing capability, the traditional echo information processing platform has been difficult to meet the requirements of technological development. Based on the advantages of high transmission bandwidth, rich I/O resources and strong scalability of VPX bus, this paper proposes a design scheme of echo information processing platform based on VPX bus, focusing on the composition of information processing platform and the design principle of each functional module. Based on the idea of dataflow driving, a new peer-to-peer backplane architecture is adopted. The test results show that the information processing platform only needs 20.2s to complete 32K*32K complex image processing. The performance is superior, stable and reliable.
