摘要
针对复杂雷达信号环境模拟系统中对多输出、多调制形式的波形产生单元的迫切需求,综合了以小波变换为基础的脉内调制特征提取技术和以DDS技术为基础的直接数字调制波形合成法,借助于SOPC技术,设计完成了一种新的波形产生单元。
A new waveform generation unit is designed. The unit can output several signals with different modulation modes simultaneously,which lays a good foundation for simulating complex signal environment, In the unit,DDS, SOPC and modulation characteristics extraction technologies based on wavelet transform are employed, .
