摘要

未来的雷达系统必须适应动态频率约束，同时最大化目标探测距离。然而，提供最佳功率的阻抗终端随着频率和阵列扫描角度的变化而显著变化。为了在工作频率和扫描角度变化时保持良好的检测范围，我们介绍了在发射功率放大器和发射天线之间使用大功率可重构电路。该可调谐匹配网络及其快速调谐算法将在软件定义无线电(SDR)平台的控制下实现，以实现实时优化。

Real-Time Circuit Reconfiguration for a Cognitive Software-Defined Radar Transmission: A New Paradigm in Spectrum Sharing

Future radar systems will must adapt to dynamic frequency constraints while maximizing target detection range. However, the impedance termination providing optimum power changes significantly with frequency and array scan angle. To maintain good detection range over operating frequency and scan angle changes, we introduce the use of high-power reconfigurable circuitry between the transmitter power amplifier and transmit antenna. This tunable matching network and its fast tuning algorithms will be implemented under the control of a software-defined radio (SDR) platform to allow real-time optimization.
