Abstract

A method for determining the output of the thermal mode control of an active phased antenna array of an electronic device operating in a highly elliptical orbit is presented. The proposed method allows constructing an optimal cyclogram of the active phased antenna array heaters operation. This method uses modified Fourier series constructed using a new class of orthonormal function systems.

This method allows for an optimal temperature pattern and temperature change of the active phased antenna array components over time, which minimizes the risk of emergency situations related to the active phased antenna array thermal conditions when operating in orbital flight conditions.

Within the framework of this task, an additional analysis of the method for determining the transmitted power of the loop heat pipe in the active phased antenna array radiative heat exchanger based on temperature sensor readings for the case where the measurement power quickly changes over time during the period of the equipment's revolution around the Earth.

The operability method is confirmed based on a mathematical model of thermal processes in active phased antenna array designs.

基于改进傅立叶级数的有源相控阵热流随时间快速变化的热控制模式

提出了一种确定在高椭圆轨道上工作的电子器件的有源相控阵热模控制输出的方法。所提出的方法允许构造有源相控阵天线加热器运行的最优环图。该方法采用了由一类新的正交函数系统构造的改进傅立叶级数。该方法允许有源相控阵天线组件随时间的最佳温度模式和温度变化，从而最大限度地减少在轨飞行条件下运行时与有源相控阵热条件相关的紧急情况的风险。在本任务的框架内，对在设备绕地球旋转期间测量功率随时间快速变化的情况下，基于温度传感器读数确定有源相控阵辐射热交换器中环路热管传输功率的方法进行了额外的分析。基于有源相控阵热过程数学模型，验证了该方法的可操作性。
