| Abstract: | Automatic level control（ALC）circuits are the key components of wideband radar signal source system,ensures the power flatness,accuracy and resolution.This paper presents a new digital broadband and wide dynamic range ALC design project,gives the design and realization of key circuits and ALC algorithm.Based on the fusion optimization design of ALC system and signal source channel,the better performance index is fetched.The test result indicates that this design project achieves better spectrum purity power flatness and has been applied to the engineering practise. |
