Global correlation envelope alignment of high precision

摘要：

Envelope alignment is the foundation of ISAR motion compensation. Algorithm of global correlation envelope alignment is improved in this paper by using the character of Fourier transform frequency shifts. By using the algorithm proposed by us completes range rough alignment at first, then adjusts the range profile which has been aligned rough within some of the imaging pulses according to frequency shifts factors, the accuracy is enhanced through this algorithm. Keywords: isar, motion compensation, correlation
