摘要
结合实际的线性调频(Chirp)信号形成器,介绍一种应用直接数字合成技术(DDS)实现的复杂雷达波形生成方法,并对影响输出信号质量的因素进行了分析。利用这种方法可产生高稳定的复杂雷达波形。经调制,可用于雷达的发射波形合成,也可直接用于雷达的视频回波模拟。
A method of complex radar signal generation based on Direct Digital Synthesis is introduced in this paper. An analysis of the factors that affect the output signal quality is also made as well. This approach can be used to generate highly by stabilized radar Chirp signals as well as other complex radar signal waveforms which after modulating processing may be used cither as a transmitter signal generator or as a simulator of output signals of a radar receiver.
