摘要
为了解决功放设备或环境等因素的变化对短波Chirp探测激励器输出功率造成影响的问题,通过分析输出射频、实际功率与目标功率三者之间的相关联性,采用差值迭代的方法,提出了自适应输出算法。经仿真实验证明,自适应输出算法可以自动调整射频,使得实际功率逐渐趋近目标功率,避免因外部因素给射频功率带来的影响,具有较好的适应性和实用性。
In order to deal with the impacts of the change of the power amplifier equipment and the environment on the output power of HF Chirp detection exciter, the relationship of the output RF, actual power and target power was analyzed and the adaptive output algorithm was put forward based on the difference iteration. Simulation experimcnls demonstrate that the proposed method can automatically adjust RF, make the actual power approach tile target power and avoid the impact of the external factors on the RF power. Therefore, the proposed method has the better self-adaption and practicality.
