典型待测航电射频设备辐射仿真数据、辐射测试数据集

数据采集于2022年1月-2023年6月，采集地点为陕西省西安市长安区西安电子科技大学电磁兼容实验室。设备主要为实验室计算机、电磁兼容实验室微波测量设备、待测天线样机。仿真数据通过CST仿真多种孤立航电天线模型，结合SAVANT软件分析不同类型的射频设备在机载条件下的辐射与耦合模型；测试数据主要通过微波暗室进行数据采集，其中天线E面方向图采集方法：将喇叭与待测天线最大辐射方向和极化方向对准（圆极化天线只需保持最大辐射方向对准），喇叭与矢量网络分析仪1端口连接，待测天线放置在转台上与端口2连接，启动转台得到E面方向图；H面方向图采集方法：将喇叭与待测天线极化方向对准，天线旋转90°使H面与喇叭对准。再次启动转台得到H面方向图。测试数据包括测试2.4 GHz线极化全向/定向天线S11，驻波比以及方向图；测试2.4 GHz圆极化极化全向/定向天线S11，驻波比，方向图以及轴比；以及相控阵设备样机在待机条件下的10kHz-18GHz的辐射数据。The data was collected between January 2022 and June 2023 at the Electromagnetic Compatibility Laboratory of Xidian University, Chang'an District, Xi'an City, Shaanxi Province. The main equipment used includes laboratory computers, microwave measurement equipment in the Electromagnetic Compatibility Laboratory, and antenna prototypes to be tested. The simulation data was generated by simulating multiple isolated airborne antenna models using CST, and analyzing the radiation and coupling models of different types of RF equipment under airborne conditions with SAVANT software. The test data was mainly collected in an anechoic chamber. The collection method for the antenna E-plane radiation pattern is as follows: align the horn antenna with the maximum radiation direction and polarization direction of the antenna to be tested (for circularly polarized antennas, only align the maximum radiation direction is required), connect the horn antenna to port 1 of the vector network analyzer, place the antenna to be tested on the rotary stage and connect it to port 2, then start the rotary stage to obtain the E-plane radiation pattern; The collection method for the H-plane radiation pattern is as follows: align the horn antenna with the polarization direction of the antenna to be tested, rotate the antenna by 90° to align the H-plane with the horn antenna, then start the rotary stage again to obtain the H-plane radiation pattern. The test data includes: S11 parameters, voltage standing wave ratio (VSWR) and radiation patterns of 2.4 GHz linear polarized omnidirectional/directional antennas; S11 parameters, VSWR, radiation patterns and axial ratios of 2.4 GHz circularly polarized omnidirectional/directional antennas; as well as radiation data of phased array equipment prototypes in standby mode within the frequency range of 10 kHz to 18 GHz.
