【摘要】 针对船用导航雷达的海杂波抑制、雷达探测范围和盲区之间的矛盾问题，设计了一款脉内双频点、脉间频率捷变三脉冲拼接的导航雷达信号处理机，通过多频点抑制海杂波，多个脉冲互相补盲，可以最大程度发挥雷达的探测功能的同时又减少雷达的近程探测盲区。经过上板实测，抓取系统工作波形图分析，系统产生的信号波形符合项目要求，获取的雷达目标清晰有效，表明系统功能的有效性，符合设计预期的功能和性能。更多还原

【Abstract】 In response to the conflicting issues of sea clutter suppression,radar detection range,and blind spots in marine navigation radar,a navigation radar with intra pulse dual frequency points and inter pulse frequency agile three pulse splicing is designed. By suppressing sea clutter at multiple frequency points and compensating for blind spots with multiple pulses,the radar’s detection function can be maximized while reducing the radar’s close range detection blind spots. After actual testing on the board,the waveform analysis of the grasping system shows that the radar waveform generated by the system meets the project requirements,and the obtained radar targets are clear and effective,indicating the effectiveness of the system’s functions,which meets the expected functionality and performance of the design.更多还原
