论文摘要
提出了一种具有2位相变的新型单层（SSB）时间调节技术。通过将定期相调制添加到2位相位变速器中，该模块是实现的，与现有的SSB时间调制方法相比，这更简单而没有性能损失。在一个调制期间，2位相变的四个相状态（0，π/2，π，3π/2）序列切换。调制后，实现了SSB时间调制，主功率分布在第一个谐波组件中。通过实验验证了所提出方法的可行性。不希望的谐波被有效抑制。同时，通过提出的模块实现了80°光束扫描范围。
A novel single-sideband (SSB) time-modulated technique with 2-bit phase shifters is proposed. The timemodulated module is implemented by adding periodic phase modulation to 2-bit phase shifters, which is simpler without performance loss compared to existing SSB time-modulated method. During one modulation period, four phase states (0, π/2, π, 3π/2) of 2-bit phase shifters are switched in sequence. After the modulation, the SSB time modulation is realized and the main power is distributed to the first harmonic component. The feasibility of the proposed method is verified by experiments. The undesired harmonics are efficiently suppressed. Meanwhile, 80° beam scanning range are realized through the proposed module.
