Two-beam Scanning Method Based on Injection-Locking Technique

This paper studies Two-beam scanning system of nonlinear active array based on injection-locking technique, which has the merits of miniaturization, low cost, high integration. Firstly, the article reviews the theory of injection-locked phase, then analyzes basic method of two-beam scanning, computer simulations are used to verify the realization. At last, four channels injection-locking oscillators is designed and the validity of two- beam scanning system is also validated by the measurement of radiation pattern.
