Abstract: The system and method of projectile flight management using a combination of radio frequency orthogonal interferometry for the long range navigation and guidance of one or more projectiles that does not need to be accurate all the way to the ground based on the use of larger artillery. The system provides for more accurate targeting, especially in GPS-denied and GPS-limited environments.

Abstract: Techniques are provided for mitigating interferometric angle ambiguity. A methodology implementing the techniques according to an embodiment includes measuring a differential phase of a signal received at an interferometer baseline; calculating a Gaussian conditional probability of an angle of arrival of the signal based on the differential phase; calculating an angular position probability of an object in a target reference frame based on the conditional probability; aggregating the angular position probability with previously calculated angular position probabilities (based on previously selected baselines) to generate a current angular position probability; selecting a next baseline and iterating the process to calculate a next angular position probability; and selecting an angular position probability of greatest likelihood, from the current and previously calculated angular position probabilities, based on an amplitude of the Gaussian distributions, such that the selected angular position probability is associated with a disambiguated angular position of the object.

Abstract: A system and method for using coherent aggregated bandwidth over multiple transmissions for improved performance of precision guidance and positioning and of object tracking systems. Angular offset (Az/El) estimations are strongly impacted by interference between direct and (comparable amplitude) ground-reflected signals. In rough ground situations, there could be many ground reflected signals. Bandwidth aggregation as used herein achieves sharper range sidelobes and smaller magnitude multipath interference terms resulting in increasingly accurate interferometric results.
