摘要
某型直瞄炮射导弹试验中需要进行导弹参数的遥测,该导弹弹道接近地面,信号多径传输严重且炮射发射初始过载大,常规遥测系统难以满足使用要求。直序扩频具有良好的抗干扰和抗多径能力,因此研制了一种直序扩频遥测系统,并针对遥测舱大过载的使用环境进行了针对性设计。该遥测系统已经通过实弹发射试验,试验证明该遥测系统满足大过载使用要求,系统初始捕获速度快,抗多径能力强,遥测数据准确可靠。
A parameter collection is needed in some direct aiming cannon-launched missile test. But traditional telemetry cannot satisfy both the low trajectory muhipath transmission and initial launch overload. So a direct sequence spread spectrum（DSSS） telemetry system is designed because of its ant-jamming and anti-muhipath capability. Taking the rigorous overload into consideration, special attention is paid to the telemetry section. This system has been tested in field launch test. Its result shows that it meets the need of high overload, fast in- itial capture speed, strong anti-muhipath capability and accurate and reliable data collection.
