| 摘要: |
| 针对工程应用中单脉冲雷达差斜率简便测试问题，提出了一种正弦波单脉冲差斜率测试方法。推导了将非相参的正弦波信号用于差斜率测试的公式，并将正弦波信号直接用于单脉冲给差斜率测试系统，实现对单脉冲雷达系统参数的快速校正。仿真结果表明，经过该方法校正的单脉冲雷达系统可实现优于0.01??的测角精度。该测试方法能够实现高精度的系统测试性能，对解决工程应用中的测试校正问题具有实际指导意义。 |

| Abstract: |
| In view of the expediently testing problem for the slope of difference pattern for monopulse radar system in practical project, a testing method for the monopulse slope of difference pattern based on the sine wave is presented. Formulas are derived based on the non-coherent sine wave, meanwhile the testing system for monopulse radar based on the non-coherent sine wave is introduced and the testing method can rapidly calibrate the parameter errors of monopulse radar system. Computer simulation proves that the corrected radar system can obtain the angle measurement accuracy higher than 0.01??. The method achieves higher accuracy of the testing system and it is instructive for solving test and calibration problems in monopulse radar in practical project. |
