论文摘要
由于阵列扫描角变化而导致天线阻抗的变化，可能会导致明显的雷达范围降解。元素可重新配置的阻抗调谐器可用于最佳匹配功率放大器设备；但是，阻抗匹配也会影响阵列模式。在本文中，研究了元素阻抗调谐对传输能力和阵列模式的影响，建议采用一种方法来实现阻抗调谐器的元素实现。使用设计的Switch-stub阻抗调谐器的模拟给出了对阵列模式和传输功率影响的示例。这些实验的结果是，制定了用于在阵列元素中创建实时电路优化技术的准则。
Significant radar range degradation can be incurred due to variations in antenna impedance from changing array scan angle. Element-wise reconfigurable impedance tuners can be used to optimally match the power amplifier device; however, the impedance matching can also affect the array pattern. In this paper, the effects of element-wise impedance tuning on the transmitted power and on the array pattern are studied, and an approach is recommended for the element-wise implementation of impedance tuners. Examples of impact on array pattern and transmitted power are given using simulation of a designed switched-stub impedance tuner. As a result of these experiments, guidelines are developed for the creation of real-time circuit optimization techniques in the array elements.
