针对压缩感知(compressive sensing, CS)技术在成像雷达中的应用,基于FPGA研究了压缩感知非相关测量框架的数字化电路设计,提出并实现了基于雷达回波模拟信号源的信息转换器(Analogue-to-Information Converter, AIC)功能的测试方案。通过对实际获得的压缩数据进行处理获得了符合预期的结果,验证了AIC电路作为一种数据压缩方法数字化设计的有效性。 |

Research on digital modeling and realization of non-correlation measurement frame for compressive sensing (CS) was conducted aiming at applying CS to imaging radar, and FPGA based Analogue-to-Information Converter (AIC) was proposed and implemented. Real measurement data from AIC hardware platform and simulation data from AIC software platform were compressed to get range profiles and the results are agreed well with what expected. Simulation results show that FPGA based Analogue-to-Information Converter is a validated data compression method in the radar application. |
