针对机载防撞系统( TCAS)空对空通信时存在的同步混扰，采用飞机分布因子结合问询功率和问询速率的控制方法，建立了干扰限制的数学模型，给出了TCAS监视功能干扰限制的设计流程。按照DO-185 B标准定义的高密度飞机分布环境，采用计算机仿真得到了TCAS干扰限制功能在高密度空域中统计性能，对不同监视区域中TCAS应答机的占用率与DO-185 B的设计需求进行比较，验证了设计的干扰限制功能的有效性和实用性。仿真结果表明干扰限制算法能够满足高密度空域中TCAS监视功能的要求，在TCAS干扰限制功能的设计和性能评估方面具有实际应用价值。

The mathematic models of interference limiting are established by utilizing distribution factor of aircraft combined with the control of Traffic alert Collision Avoidance System ( TCAS ) interrogation power and rate which are resulted from air-to-air communication in TCAS,and the interference limiting proce-dure in TCAS surveillance function is discussed in detail. According to the high traffic-density environment defined in DO-185B standard,the computer simulations are used to characterize the statistical performance of the TCAS interference limiting function in high density airspace. Transponder utilization due to TCAS and TCAS surveillance range is compared with the interference limiting design requirements to verify the ef-fectiveness and practicability of the interference limiting function design. The simulation results indicate that the interference limiting algorithm meets the requirements of the TCAS surveillance function in high density airspace and it has actual application value on the design and performance evaluation of TCAS in-terference limiting function.
