Design and implementation of a seeker signal processor based on FPGA and DSP

The seeker signal processor is a key device of a seeker. Based on the common characteristics extracted from seekers with different architectures, a general-purpose hardware scheme based on Field-Programmable Gate Array (FPGA) and Digital Signal Processor (DSP) is proposed. By taking full advantage of the FPGA and the DSP, the signal processor is equipped with the ability of high speed and real-time signal processing. Because of the space limitation inside the seeker, the principle of miniaturization and low power consumption should be followed. At the same time, online updating and dynamic loading of the program can be easily achieved through the serial peripheral interface, which makes the debugging process easier.
