Appl. No.:

13/092252

Assignee:

Vanderbilt University - Nashville TN

International Classification:

G01S 3/80

US Classification:

367127, 367118

Abstract:

Systems and methods for estimating projectile trajectory and projectile source location are provided. A method for estimating location information associated with a supersonic projectile propelled from a source includes recording sound at a first location using a single microphone during travel of the supersonic projectile to produce an acoustic recording. The method further includes estimating a miss distance between the first location and a trajectory of the projectile based on the shockwave length. Locating a projectile source includes concurrently recording sound at multiple locations and generating data sets associated with the locations, each of the plurality of data sets including a miss distance, a range, a time of arrival of a muzzle blast from the source, and a time of arrival of a shockwave produced by the projectile. Additionally, the method includes calculating an approximate location of the source at each of the locations based on the data sets.

Abstract:

Aspects of the present invention relate to methods and systems for high-accuracy differential tracking of global positioning system (GPS) receivers. In one embodiment, a network having multiple receivers is provided. The receivers are configured to communicate with each other. The receivers in the network are configured to measure raw satellite data, and to share the raw satellite data measured by each receiver. Each receiver is configured to process the measured raw satellite data with a Peak Ambiguity Function Value (AFV) Tracking Solution (PATS) to track relative motions of the neighboring receivers so as to derive relative location information for the plurality of receivers.
