A GA-based autofocus technique for correcting high-frequency SAR phase error

The presence of a space-invariant sinusoidal phase error in the azimuth SAR (synthetic aperture radar) signal history causes paired echoes to appear in the system impulse response [1]. These high peak sidelobes may be interpreted erroneously as separate targets by conventional autofocus algorithms....
