中文摘要:
      相位测试技术可满足不同外形天线罩的在线测试需求。通过数值仿真,设计最佳变换曲线完成矩形 传输波导与圆形辐射天线的拟合连接,能够有效降低天线驻波比,实现测试探头的高增益收发,提升测试有效性。 在维持驻波比参数前提下,对天线口面弧线给予二次曲率调整,可以适应不同外形天线罩的测试稳定性要求。根据 仿真结果加工的低驻波比反射相位测试天线,已应用于多个型号天线罩成型中的相位在线测试,提高了监控的有效 性,验证了设计仿真结果的正确性。
英文摘要:
      Phase testing technology can meet the online test demands of radomes in different shapes. Designing the optimal transformation curve to complete the fitting connection between the rectangular transmission waveguide and the circular radiation antenna via numerical simulation can effectively reduce the antenna voltage standing-wave ratio (VSWR), achieving the high-gain transceiver for the test probes, improving the test effectiveness. In the condition of maintaining the VSWR parameters, secondary curvature adjustment for the antenna aperture can accommodate the test stability requirements of radomes in different shapes. Low-VSWR reflection phase test in the molding of multiple radome models, which improves the effectiveness of monitoring and verifies the correctness of simulation results.
