随着雷迭发射机技术的不断发展，越来越多的新技术应用于发射机设计中。复杂可编程逻辑器件CPLD和现场可编程门阵列FPGA，同以往的PAL和GAL器件相比，这些器件舍有数量众多的可编程逻辑宏单元或逻辑块，规模大，组合能力强，设计成功能各异的逻辑电路，适舍于时序、组合等逻辑电路。本文用CPLD对发射机控制功能进行综合处理，控制命令产生部分根据信号处理机通过串行链发来的控制命令产生控制命令，然后对发射机进行相应的控制，并对相关命令根据时序和故障情况进行逻辑链锁，达到最终控制发射机的目的。

With the developing of the technology of radar transmitter, more and more new technology application in design of the transmitter. Compare with the GAL and PAL,Complex programmable logic device CPLD and the field reprogrammable array FPGA , these devices contain a large numbers of programmable logic macroelements or logical blocks, with the large scale, with the good ability of combination, designed to logic circuit of different function, suitable for the logic circuit of the timing sequence and combination.In this paper,the CPLD comprehensively processes the control function of the transmitter, the control command produce parts produce the control command according to the signal processor,then it ...
