针对弹载遥测设备处于飞行黑障区时各种干扰因素造成的遥测信息短时中断、数据丢帧的问题，提出了基于现场可编程门阵列的弹载遥测记忆重发器。以软件处理方式代替硬件处理，在不增加弹载遥测系统硬件电路的基础上，利用弹载遥测编码器中现有的现场可编程门阵列(FPGA)芯片将弹载遥测记忆重发器设计为编码器中的一个软件模块，该模块集数据存储、延迟发送功能于一体。仿真结果标明：基于 FPGA 的弹载遥测记忆重发器，在不改变硬件情况下通过软件在线配置即可实现记忆重发方式和重发时间的灵活编程，可以满足不同的测试要求。飞行试验结果表明：该记忆重发器解决了无控火箭弹遥测系统处于黑障区时的遥测数据可靠接收问题，工作性能可靠，可直接推广应用到其他弹载遥测系统测试中。

When the missile-borne telemetry system works in the blackout zone,which causes telemetry infor-mation short interruptions and lost frame telemetry data.To solve the problem,a missile-borne telemeter mem-ory retransmitter based on field programmable gate array was proposed.The hardware approach was instead by software without increasing the missile-borne telemetry system hardware.The missile-borne telemeter memory retransmitter was designed for a software module using existing FPGA chip on telemetry encoder,which had data storage and delay sending functions.The simulation results indicated that the memory retransmitter could change memory retransmission mode and time of retransmission by flexible programming without changing the hardware.Flight test results showed that the memory retransmitter solved telemetry data reliable reception problems when no control rocket telemetry system worked in the blackout zone ,it ould be directly extended to other missile-borne telemetry system testing.
