中文摘要：针对合成孔径雷达系统面临的场景散射等干扰无法使用传统时、空、频域技术抑制的问题，提出了一种基于线性调频信号调频斜率极性捷变和限幅过程相结合的抗干扰方法。

Some technical problems arose during the debugging of the accelerator. The ion source did not produce arc. The accelerator tube cracked. The control system was out of order. The transporting capacity of the charge belt degraded. The corresponding reasons were analyzed and some measures were adopted to solve the problems. The drawing voltage was raised to its predetermined position after the ion source produced arc and should be reduced to zero before turning off the accelerator. Transition flange was lathed and the accelerator tube was re-assembled. The control equipment at high voltage was shielded. TVS diodes were installed at the input and output ends.

调试中出现了离子源不起弧、加速管破裂、控制系统失灵和输电带输电能力降低等技术问题，分析了出现这些问题的原因，然后分别采取了相应的措施加以解决：变换工作流程，在每次关机前先把引出电压降为零，开机时等离子源起弧后再把引出电压升到预定值；对过渡法兰进行车加工，重新封装；对高压端的控制设备采取屏蔽措施，在输入、输出端使用TVS二极管，对控制软件进行抗干扰设计；对绝缘气体进行循环干燥等。
