Two applications of space-time adaptive processing are addressed: clutter rejection for ISAR by a moving radar, and jammer cancellation for broadband radar like SAR. It is shown that for both problems the space-time covariance matrix has a similar form. The effect of space-time FIR filtering on the resolution capability of ISAR and SAR is analysed. It appears that distortions of the point spreading function mainly appear close to the clutter (or jammer) notches of the adaptive filter, i.e. in areas where the filter transfer function is not constant with Doppler (angle)
