Abstract

This paper discusses application of a cross-channel interferogram based technique for target geolocation to data from the Gotcha sensor. A modified SAR/ATI/STAP geolocation method is used to compensate for the inability to perform STAP well using the available Gotcha data due to limitations in spatial degrees of freedom. SAR/ATI geolocation is illustrated with three examples from the measurements for: two known targets with truth data, and an unknown target. The first known target is geolocated with a 15.6m accuracy; the unknown target is geolocated with reasonable accuracy for 8 out of 11 detections; and the second known target is geolocated with an average error of 13.18m for 10 consecutive CPIs.
