摘要
We present a modification to the adaptive Goldstein radar interferogram filter which improves the quality,of interferometry products. The proposed approach makes the Goldstein filter parameter alpha dependent on coherence, such that incoherent areas are filtered more than coherent areas. This modification minimizes loss of signal while still reducing the level of noise.
