本文提出了一种使用现代科学仪器检测船载导航雷达收发机的测试系统方案。通过对船用导航雷达收发机的结构和关键测试项目的分析,提出了针对收发机主要技术参数:载波频率,信号带宽,谐波指数,发射脉宽和频率,峰值发射功率,噪声系数,动态范围,最小灵敏度的测试方案;并对基于该方案的测试方法做了详细探讨。测试结果表明,该系统测试方案简单可靠,结果稳定准确,对导航雷达的研究和生产都具有重要指导意义。

The article proposes a kind of test system of navigation radar transceiver unit by using modem scientific instruments. Through analyzing the transceiver's structure,we design the test plan of the key parameters including carrier frequency,signal band width,spurious parameter,peak power,noise coefficient,the dynamic range and the sensitivity.Then we make detailed discussion of the measurement method based on this plan.The test results indicate that the system test plan is simple and reliable; the result is stable and accurate.Moreover it has the important guiding sense to the research and production of navigation radar.
