脉冲压缩技术在无线电定高引信中的应用

无线电定高引信作为一种重要的引信得到了广泛应用。作为一种以高度来控制引爆的引信,定高精度是其一个主要的指标。为得到较高的距离精度,目前使用窄脉冲作为发射信号,导致功率不高,作用距离有限。为了在获得高距离精度的同时提高引信的作用距离,必须采用脉冲压缩技术。本文对目前无线电定高引信的系统进行改进,在发射端采用线性调频方式发射宽脉冲信号,在接收端采用脉冲压缩技术对电路系统作分析推导,得到主要设计参数,并对信号进行仿真,得到了和理论分析相同的结果。

The Application of Pulse Compression Technology in Radio Altimeter Fuze

Radio altimeter fuze is widly used as a kind of important fuze, which controlles initiation based on the height.The altimeter precision is a main index.Very narrow pulse launch signal is used to achieve it,which results in the power be low and the action range be short.For enhancing the range height and holding the power,the technology of pulse compression must be used.For improving the capability of the radio altimeter fuze system,the linear frequency is used in the transmitter wide pulse signal and the te...
