Abstract :
We extend the amplitude and phase estimation (APES) adaptive filter of Stoica et al. (see IEEE Signal Processing Lett., vol.6, p.205-206, Aug. 1999 and IEEE Trans. Signal Processing, vol.48, p.338-52, Feb2000.) to the multiple look scenario. Several important radar and sonar applications can benefit from the new multilook APES filter. The properties of the APES algorithm allow for the accurate solution of the layover problem and the undistorted estimation of radar reflectivity for topographic mapping by means of multibaseline interferometry
