Design of Missile-borne Radar Signal Processor SoC and Its Implementation

In order to meet the demand of system real-time, this paper designs a programmable SoC scheme of missile-borne radar signal processing system, where, by employing the SoC technique, the specific application modules for radar signal processing are integrated in a single chip as far as possible, thus improving its versatility. In the scheme, A/D sampling, DDC, PC, MTD, CFAR and other functional modules are integrated into a FPGA chip that has an embedded CPU hardcore, on which the testing and checking are performed. Meanwhile, by taking the performance improving strategy, the on-chip system performances are improved and the real-time demand for signal processing is met. Test analysis shows that this proposed chip has advantages of fast-processing capability, larger data storage capacity and less power consumption as well as super communication rate between modules in the chip.
