摘要
现有的多RR系统应答机在某些飞行段落中,由于接收信号变差,导致三路转发信号同时出现跳变,为此,提出了三路全相参设计思路,介绍了应答机设计方案。分析和试验结果表明,该方案在大幅简化电路设计的同时还能够保证测速精度。
In some flight passages,existing transponders of n-RR system lead to the simultaneous jump of three-way transmit signals due to the deterioration of the received signals.To solve the problem,a threeway full coherent design idea is proposed and the transponder design scheme is introduced.The theoretical analysis and test results show that the scheme can ensure the velocity measurement precision while simpli-fying the design of the circuit greatly.
