| 摘 要： | 现有自适应干扰对消系统理想对消速度模型不能描述系统稳定性问题。为此，引入系统稳定性条件修正对消速度模型。考虑了电调衰减器射频响应特性对对消速度的影响，进一步修正对消速度模型。结合仿真与实验对对消系统稳定性问题及电调衰减器射频响应特性进行测试，验证了修正模型的正确性。修正模型对后续样机的对消速度性能设计的参数分配具有参考意义。

| Abstract: | The cancellation speed model is modified by adding the system stability condition because the ideal cancellation speed model cannot describe the system stability problem.By considering the influence of the radio frequency response characteristics of the electronic attenuator on the cancellation speed,the cancellation speed model is further modified.Through simulation and experiment,the correctness of the modified model is verified.The modified model has reference significance for the design of parameters of following prototypes. |

| Keywords: | adaptive interference cancellation(AIC) cancellation speed mode electronic attenuator |
