摘　　要：首先介绍了Link16数据链信号的特点,指出了原有Link16数据链信号检测方法的不足之处,然后根据MSK调制的特点提出了一种基于Goertzel算法的改进方法。这种方法可以有效剔除原方法对非MSK调制信号的错误判决,并且运算结构简单,适合FPGA实现。Firstly,the feature of Link16 signal is introduced,and the defection of original detection meth-od for Link16 signal are pointed out,then an improved detection method based on Goertzel algorithm is proposed according to the feature of MSK modulation.The Improved method can effectively eliminate the mistakes of original detection method,and have a simple operational structure easy to implement in FPGA.

关 键 词：LINK16 GOERTZEL算法 MSK调制
