摘要

提出了一种利用ｃｈｉｒｐ调解器改进ＡＬＥ系统性能的方案，根据军标的要求和ＡＬＥ系统的特点，对基于ｃｈｉｒｐ调解器的ＡＬＥ系统进行了全面的优化设计．通过大量实验对比了两种调解器及相应ＡＬＥ系统的性能，验证了ｃｈｉｒｐ调解器实现ＡＬＥ功能的优越性．

Abstract

The characteristic of the ALE technique in MIL STD 188 141A is analyzed first to overcome the shortcomings of 141A’s 8FSK ALE Modem.Then a new type of ALE modem using a low rate DPSK modulation is designed to replace the 141A system.For comparison

the parameters of the chirp modem are set according to the 141A8FSK modem.From a large amount of data from the testing of these two modems

the good performance of the chirp modem to transmit data and its function of LQA are verified.The conclusions prove that chirp modem is a good ALE modem.
