一种新型某导航模拟器的设计与实现

Design and Implementation of New Kind of Navigation Simulator

某导航模拟器是内场试验环境下构建密集、复杂多变某导航设备电磁环境的必要手段。为解决传统模拟器体积重量大、造价昂贵等缺陷,设计基于新一代全可编程片上系统(ZYNQ)+AD9361的新型模拟器。通过上位机对AD9361进行控制,模拟某导航模拟器功能。经测试,该模拟器实现某导航设备信道全覆盖,输出功率较高,可构建多项内场某导航设备电磁环境。

A navigation simulator is a necessary means to construct a dense,complex and changeable electromagnetic environment of a navigation equipment in an internal field test environment.In order to solve the defects of traditional simulator,such as large volume,high weight and high cost,a new simulator based on ZYNQ-7000 All Programmable Soc(ZYNQ)+AD9361 is designed.The AD9361 is controlled by the upper computer to simulate the function of a navigation simulator.The test results show that the simulator can achieve full channel coverage of a navigation device with high output power,and can construct electromagnetic environment of a navigation device in multiple internal fields.
