Abstract :
This paper researches on the method of fusion imaging based on echoes from multiple frequency band radars. When using wideband LFM signal, an applied algorithm is presented. Echoes data from multiple radars are used to the fitted model, and high resolution is achieved by using modern spectral estimation techniques. This approach is validated by theoretical analysis and the result of static range experiments. At last, a fusion range profile of a plane by two different frequency wideband radars is given.
