基于AD9910的调频非线性步进信号生成方案
Scheme for Nonlinear Stepped-Frequency Chirp Signal Generation Based on AD9910
摘要
Abstract
Nonlinear stepped-frequency chirp signal has good performance on suppression of sidelobes and grating lobes. The constraint conditions on parameters, e.g. , pulse width, pulse repetition interval, total signal bandwidth, etc, are analyzed from the view of implementability as well as in consideration of the abundant waveform generating function of AD9910. Different waveform implementations have significant effects on the performance indices of signal and the system design of waveform generation. Finally, the best scheme of waveform realization applying to AD9910 is introduced by comparing the different schemes. This paper provides an theoretical basis and technical reference to the waveform design and the scheme choice of the signal generation on nonlinear stepped-frequency chirp signal.关键词
