| Abstract: | The generation method of digital delay signals based on DDS is presented.The stable directivity of antenna patterns at different frequencies is implemented through the time delay of broadband LFM signals,on the basis of which the nonlinear iteration algorithm for DDS nucleus is designed according to the principle of DDS signal generation.The simulation test verifies the effectiveness of the algorithm. |
| Keywords: | radar LFM signal DDS digital delay beam directivity |
