Abstract: A methodology for initial orbit determination of an object about an astronomical body searches a grid of possible boundary values on the range-to-object over the observation interval to find the grid point and corresponding initial orbit that best fits all of the more than three (N) angles-only observations according to an error metric. The search is conducted by solving a boundary-value problem for different grid points. The state vector is propagated to determine estimated observation directions for the remaining N−2 observations. The grid point (and initial orbit) that best fit all of the observations is selected. For efficiency, the search may start with a broad but coarse initial grid and increase the resolution of the grid as the search converges to a solution.

Abstract: Described are methods and systems for vicarious polarimetric calibration and performance validation of a remote sensor. The system includes a plurality of reflective mirrors configured and arranged to reflect radiation from a source of radiation onto the remote sensor with accurately known polarimetric properties. Each of the reflective mirrors are located so that the target images do not overlap. The remote sensor is configured to receive the radiation reflected from the plurality of reflective mirrors and store the received radiation as image data (e.g., the image of each mirror appears as a point target). The system includes a processor configured to process the received data to provide direct calibration and performance validation for each polarimetric or spectral channel of the remote sensor. In addition, the calibration method removes all atmospheric effects except for transmittance and provides reference targets that have high polarimetric contrast, full spectrum performance and easy to deploy.

Abstract: A method of image processing for finding a target in a scene includes receiving a series of images from a sensor and computing a background relative velocity in the series of images. The method further includes estimating a hypothesized target relative velocity of the target in the series of images. The method further includes computing a target revisit time based on a difference of the target relative velocity and the background relative velocity. The method further includes adjusting one or more of a frame capture rate or a frame processing rate based on the target revisit time.
