摘要
六端口具有测相精度高的优点,在雷达接收机中有着广泛的应用,因此对六端口测量技术的研究有着重要意义。本文比较了几种六端口测距解模糊的方法,得出六端口在测距解模糊上还存在一些不足之处。因而,本文提出了一种新的基于六端口的线性相位调制测距解模糊方法,对其进行了方案的分析和介绍。利用Advanced Design System(ADS)软件,对提出的系统进行了仿真。仿真结果验证了该方案的可行性。
Six-port, which has high accuracy of phase measurement, is widely used in radar receivers, therefore, it is important to study the measurement technique of six-port. A comparison is made with several distance measurements solving ambiguity methods of the six-port, and it shows that there are still some disadvantage in distance measurement solving ambiguity methods of six-port. A distance measurement solving ambiguity method of six port based linear phase modulation is proposed. Analysis and presentation were made in the paper. Simulations of the proposed system were made in Advanced Design System(ADS). The Simulation results verify the feasibility of the proposed scheme.
