| Abstract: | The technique for detecting, locating and imaging moving targets based on external illuminators is a very important research field in the new style radar system. Motion compensation for passive radar imaging is discussed in the paper and echo-signal models for target are given, On the basis of this, the relativity of contiguous echo-signal envelope is used for motion compensation. Object imaging is achieved by synthesizing into a wide-angle equivalent aperture the sub-apertures which are formed by the echo-signal coming from multiple television stations located at various aspect angles. Finally, the simulation results are presented. |
