Pulse compression technology is one of the key technologies in the field of modern radar signal processing, can effectively solve the contradiction between action distance and resolution. In this paper, a radar digital pulse compression system is designed and implemented based on FPGA with linear frequency modulated signal. The digital pulse compression module is designed using FFT IP core which can be reused in different periods of DPC, respectively performing FFT and IFFT calculation, so that the hardware consumption is saved significantly. Therefore, compared with other systems, the system designed in this paper has the characters of fast processing speed, high degree of modularity, real-time processing and short development cycle.

Modulation Signal

Linear frequency modulated signal and the two-phase encoded signals are widely used in pulse compression radar system derived, based on the analysis of the two signals, a linear frequency modulated with chaotic two-phase coding complex modulated signals. Versatility advantages of simple structure, radar signal processing using DSP signal processing devices. TI's TMS320C6713 DSP as the core basis works to achieve a common structure, the composite modulation signal frequency domain digital pulse compression processing, given the realization of the system block diagram and pulse pressure results. The results showed that the composite modulation signal is easy to produce and handle, and works to achieve feasible.

Processing Architecture

Most radar systems based on the structure that contains many DSP chips. The system structure is always complex, and it is difficult to update. Nowadays, multi-core processor develops very fast. Compared with DSP chips, multi-core processor has better performance in signal processing field. In this paper, we present a signal processing architecture which based on multi-core processor. Pulse compression algorithms and PCI-E bus are discussed as two important technologies. Adaptive beamforming test results show that multi-core processor is able to achieve radar signal processing.
