先前为发射器应用开发的扫描振荡器技术已成功应用于接收模式。扫描是通过一组耦合的本地振荡器中的频率失谐来实现的。提出了五元件接收阵列的设计，展示了 25/spl 度/扫描范围。该阵列由本地振荡器阵列、混频器、天线阵列和中频加法器组成。本振阵列由五个变容二极管调谐 FET VCO 组成，设计工作频率为 8.6 GHz。描述了用于低相位噪声应用的注入锁定技术。
Scanning oscillator techniques previously developed for transmitter applications have been successfully applied to the receive mode. Scanning is achieved through frequency detuning in a coupled set of local oscillators. The design of a five element receiving array is presented, demonstrating a 25/spl deg/ scan range. The array consists of a local oscillator array, mixers, an antenna array and an IF summer. The local oscillator array is composed of five varactor tuned FET VCOs which are designed to work at 8.6 GHz. An injection-locking technique is described for low-phase noise applications.
