摘要： A method for radio interference based sensor localization. In one embodiment, the method has the steps of creating an interference signal from a first transmitter and a second transmitter, measuring phase offsets of the interference signal received by a first receiver and a second receiver, respectively, and determining the locations of the first and second transmitters and the first and second receivers from the measured phase offsets.

摘要： 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.
