【摘要】 基于冲击雷达原理,采用无载波亚纳秒窄脉冲发射技术精确测量脉冲传输时间从而得到弹目距离。高速脉冲锁存技术保障测量误差小于0.2 m。8位OOK(on-off keying)编码用于排除噪声和多弹间干扰。除收、发天线外,控制电路,包括编码单元、解码单元、比较单元、延时单元和定时同步等。主要阐述了窄脉冲发生、定时和解码单元的设计。更多还原

【Abstract】 Using of subnanosecond pulse based on carrier free pulse radar can obtain missile-target distance by accurate measure pulse transmission time.A high-speed pulse latch ensures measurement error better than 0.2 meter.The 8 bit OOK modulation code is used to rule out the possibility of noise interference and multi-shell.The controlled circuit of this set includes coding,decoder,comparison,delay and synchronization.This article mainly descibes the design of narrow pulse on the occurrence,timing and decoding unit.更多还原
