【摘要】 谐波雷达可对装配有半导体和金属接点的目标进行有效探测,在人员安检、金属探伤等领域有较强应用前景。简要介绍了谐波雷达的基本原理,讨论了谐波雷达的设计体制,提出了一种基于FPFA的谐波雷达设计方案。设计的谐波雷达采用线性调频脉冲体制,通过数字去斜、脉冲积累和恒虚警检测等操作实现目标探测,最后通过与Matlab仿真结果对比,验证了设计的谐波雷达可有效探测非线性目标。更多还原

【Abstract】 The harmonic radar has a good application in security inspection and metal flaw detection,because it can detect the target effectively which equipps with semiconductor and metal contact point.This paper introduces the theory and introduces a harmonic radar solution based on FPGA.The designed harmonic radar uses linear frequency pulse system.The echoes are processed by digital de-chirp,pulse accumulation,constant false alarm rate detection.In the end,the result is compared with the Matlab simulation result which verifies the effectiveness of the designed harmonic radar in nonlinear target detection.更多还原
