Abstract

The invention provides a template phased array seeker digital beam forming processor, comprising a fiber interface FPGA processing board and a double-DSP processing board. The fiber interface FPGA processing board and the double-DSP processing board are externally connected with an SRIO switch. The fiber interface FPGA processing board and the double-DSP processing board are interconnected throughutilization of a VPX backboard. According to an MGT transceiver employing fiber modules and an FPGA, high reliability fiber transmission of ultrahigh bandwidth baseband preprocessed data is realized,and 28 ways of receiving and 16 ways of transmitting are realized. On the premise of sufficiently and rationally utilizing hardware resources of the FPGA and DSPs, a requirement for adaption to digital beam forming computing complexity and a requirement for real-time processing under a large array can be satisfied; through flexible programming of software, functions of a product are expanded; andmodule software implementation is realized.

Description

technical field [0001] The invention relates to a phased array seeker digital beam forming processor. Background technique [0002] The digital beamforming processor (DBF processor) of the phased array seeker mainly completes receiving the full-array echo data preprocessed by the intermediate frequency, calculates the digital beamforming weight coefficient and sends it to the wave controller, and then receives the primary beam of the preprocessing board Synthesize data for secondary digital beamforming, and send the generated sum and difference beams to the signal processor, waiting for target search, information extraction and other processing. Digital beamforming processors with similar functions generally design structures according to the size of the seeker Cavity, its internal circuit is designed according to the product power supply interface requirements, interface data requirements and operation processing requirements. This situation makes phased array seekers of d...
