摘　　要：Link-16数据链可以为海、陆、空平台提供安全的、抗干扰能力强的战术信息,其通信终端联合战术信息分发系统(JTIDS)采用了直接序列/快速跳频混合扩频通信技术、RS信道编码技术、CCSK基带码调制技术、MSK波形调制技术等抗干扰技术。介绍了一种采用多相滤波信道化技术来实现JTIDS脉冲信号检测的方法。硬件平台采用高速FPGA器件,实现了JTIDS信号检测,实时性能好。Link-16 provides presumably secure and jam- resistant tactical information for land, sea, and air platforms. Its communication terminal, Joint Tactical Information Distribution System（JTIDS）, is a hybrid direct-sequence/frequency-hopping spread spectrum system and features Reed-Solomon（RS） codes for channel coding, cyclic code-shift keying（CCSK） for 32-ary baseband symbol modulation, and minimum-shift keying（MSK） for waveform modulation.This paper introduces a new JTIDS pulse signal checking scheme which is based on polyphase filter channelizer. This scheme is based on high speed FPGA device and implements JTIDS pulse signal checking,its real time capability is well.
