Abstract:
|
The removal of isolation errors plays an essential role in the calibration process of radar scattering measurements. One of the most common techniques used for that purpose is time-domain filtering, also known as gating. In spite of the importance of gating techniques, however, little can be found about them in the open literature. This paper analyzes these techniques and provides the concepts required to develop them optimally. In addition, a new filtering method called chirp-z filtering (CZF) and techniques to remove remaining distortions are presented. |
