Huang Xiao-xia · Journal of Projectiles.Rockets.Missiles and Guidance · 2005
A design of stepped FM millimeter wave front-end based on DDD technique is presented in this paper,genera- tion and realization of stepped FM signal and high stable millimeter wave local oscillator are mainly discussed,and the block diagram of the stepped FM millimeter wave front-end is presented.Multiple waveform can he generated with DDS and PLL techniques without increase the complexity and cost of the front-end system,which proves the very great feasi- bility of the design.The involved hardware and soft configuration is presented,the designed front-end was tested and the results is presented.
