Appl. No.:

12/500256

Inventors:

Ning H. Lu - Parsippany NJ, US
Peter D. Steensma - Green Pond NJ, US

Assignee:

ITT Manufacturing Enterprises, Inc. - Wilmington DE

International Classification:

G01S 7/36

US Classification:

342 13, 342 42, 342190, 342191, 702 5, 702127

Abstract:

Systems and methods for monitoring and classifying RF emissions in the field include storing an electronic signature map (ESM) of a selected geographic area, where the electronic signature map includes previously detected emitter closeness measures (ECMs) in the selected geographic area. The ECMs are representative of detected sources of radio frequency energy. A RF energy emission is detected, a new ECM for that RF energy emission is created, and that the new ECM is compared with the ECMs in the ESM. That comparison may help to determine whether the RF energy emission should be considered a threat.

Ning Hsing Lu - Clifton NJ, US

Assignee:

Exelis Inc. - McLean VA

International Classification:

H04K 3/00

US Classification:

455 1, 4554561, 455513, 4551153, 4554042, 455456, 342 14, 342 16, 342 17

Abstract:

According to an embodiment of the present invention jamming energy is allocated to a plurality of emitters based on a three-dimensional (3-D) emitter geolocation technique that determines the geolocation of radio frequency (RF) emitters based on energy or received signal strength (RSS) and/or time differences of arrival (TDOAs) of transmitted signals. The three-dimensional (3-D) emitter geolocations are used to rank emitters of interest according to distance and available radio frequency (RF) jamming energy is allocated to the emitters in rank order. The techniques may be employed with small unmanned air vehicles (UAV), and obtains efficient use of jamming energy when applied to radio frequency (RF) emitters of interest.

Appl. No.:

13/111379

Inventors:

Ning Hsing Lu - Clifton NJ, US

Assignee:

ITT MANUFACTURING ENTERPRISES, INC. - Wilmington DE

International Classification:

G01S 1/24

US Classification:

342387

Abstract:

According to an embodiment of the present invention, geolocations of multiple unknown radio frequency (RF) signal sources are determined using three-dimensional (3-D) geolocation techniques. The three-dimensional (3-D) geolocation techniques obtain reliable geolocation estimates of radio frequency (RF) emitters based on energy or received signal strength (RSS) of emitter transmitted signals and based on their time differences of arrival (TDOAs) at various sensor locations. The energy based geolocations and the time difference of arrival (TDOA) geolocations are combined to determine an overall set of geolocations for multiple unknown radio frequency (RF) signal sources. The geolocation information is used to track and monitor the locations of the multiple emitters.

Assignee:

ITT MANUFACTURING ENTERPRISES, INC. - Wilmington DE

International Classification:

G01S 5/02

US Classification:

342451

Abstract:

According to an embodiment of the present invention an emitter geolocation technique determines the geolocation of a radio frequency (RF) emitter using pair-wise line-of-bearing intersections that are derived from signal-to-noise ratios of transmitted signals received at a sensor. The technique may be employed with ground based vehicle or small unmanned air vehicles (UAV), and obtains reliable geolocation estimates of radio frequency (RF) emitters of interest.

Inventors:

Ning Hsing Lu - Clifton NJ, US

Assignee:

ITT MANUFACTURING ENTERPRISES, INC. - Wilmington DE

International Classification:

H04B 1/38

US Classification:

375219

Abstract:

Enhanced reception in a communication system is achieved by applying a time domain generated time-reversed channel response to signals transmitted from a group of transmitter to a group of receivers. The time-reversed channel response is generated from a radio frequency channel response derived from signals previously received from the group of receivers, but reversed in the time domain. The time-reversed channel response is convolved with an information signal that when transmitted in a coordinated fashion from the group of transmitters, the signals arrive at each receiver in the group of distant receiving communication devices at approximately the same time where the signals coherently combine, thereby increasing signal power at the receivers. This permits detection at a greater range or with a lower bit error rate. In addition, the many-to-many configuration enables signal power from each transmitter to be focused temporarily and spatially on each receiver.
