提出了一种对耦合振荡器阵列进行电子束扫描的新技术。耦合振荡器阵列中的恒定相位级数仅通过控制最外面耦合电路的耦合相位来实现，而最里面耦合电路的耦合相位为零，并且振荡器的所有自激频率相同。非线性相动态方程的解析解仅作为耦合相的分段线性函数周期性变化。用一个工作在6.16 GHz的四元振荡器阵列对理论进行了验证。全扫描范围测量为-17/spl deg/至18/spl deg/off宽边。该扫描范围非常接近该阵列的理论上可实现的扫描范围-19.2/spl deg/至19.2/spl deg/。
The authors present a new technique for electronic beam scanning of a coupled oscillator array. A constant phase progression in a coupled oscillator array is achieved by controlling the coupling phase of the outermost coupling circuits only, while that of the innermost coupling circuits is zero and all free-running frequencies of the oscillators are the same. Analytical solution of nonlinear phase dynamic equations changes periodically as a piecewise-linear function of coupling phase only. The theory developed here is verified using a four-element oscillator array operating at 6.16 GHz. The full scan range is measured to be -17/spl deg/ to 18/spl deg/ off broadside. This scan range is very close to the theoretically achievable scan range of -19.2/spl deg/ to 19.2/spl deg/ for this array.
