Abstract :
To increase the range resolution in ISAR imaging radar, time adaptations of the MUSIC algorithm and of Capon MLM are applied on each azimuth bin. The covariance matrix of each azimuth bin is estimated from the corresponding azimuth bin of ISAR images made with different carrier frequencies to avoid cross-correlation between scatterers. Simulation results are shown as well as some preliminary measurement processings
