Patent number: 8170135Abstract: A method is provided for coordinating detection of emitted signals by a receiver with transmission of signals by a transmitter, wherein the receiver and the transmitter are located on the same platform. The receiver scans a surrounding environment to detect emitted signals in multiple frequency ranges while the transmitter transmits signals in a predetermined frequency range. The receiver may employ dwells which may be defined as receiver configurations. A dwell, when executed, may be used to detect signals in a certain frequency range. If a frequency range of the dwell conflicts with the frequency range of transmitter signals, which may result in interference of transmitter signals with detection of emitted signals, execution of the dwell may be delayed. If the frequency range of the dwell is such that transmitter signals do not interfere with execution of the dwell, the dwell can be executed.Type: GrantFiled: March 6, 2007Date of Patent: May 1, 2012Assignee: Lockheed Martin CorporationInventors: Craig A.

Then the decoy alters the received signals to generate an authentic false target and transmits a deceiving signal towards the radar threat. The radar threats locks on the decoy and follow its path.Type: GrantFiled: July 9, 2007Date of Patent: November 1, 2011Assignee: RST Reut Systems & Advanced Technologies Ltd.Inventors: Moshe Shani, Avraham Cohen, Arye Amarant, Ely Levine

Patent number: 7982655Abstract: Aircraft decoy arrangement and method for generating a decoy signal from an aircraft having an isolated decoy. An aircraft receiver detects a threat signal from a threat source targeting the aircraft.

Patent number: 7821623Abstract: A satellite surveillance countermeasure system uses an airborne platform to position a coherent radiation source above a substantial portion of the Earth's atmosphere. The coherent radiation source provides coherent radiation that is directed toward an enemy surveillance satellite, so as to reversibly deny the satellite the ability to image. By positioning the coherent radiation source at such an altitude, atmospheric attenuation and distortion are mitigated. Thus, a smaller, less powerful and less costly coherent radiation source can be utilized.

Some embodiments of the invention include a transmitter that suppresses one or more signals transmitted from a target transmitter in an RF transmission system to a target receiver in a wireless device operating in the RF transmission system to prevent, disrupt, jam, interfere with or otherwise disable an RF transmission between the target transmitter and the target receiver in the wireless device (i.e., target wireless device). These systems and methods may be used to interrupt communication, command and control of non-friendly combatant. These systems and methods may also be used to suppress RF transmissions to prevent the detonation of improvised explosive devices, or IEDs.Type: ApplicationFiled: June 25, 2010Publication date: October 14, 2010Applicant: Pegasus Global Strategic Solutions LLCInventors: Robert Haywood Brumley, II, Michael J.

Patent number: 7792218Abstract: A digital radio frequency memory (DFRM) which converts an incoming analog radio frequency signal to a fourteen bit digital signal allowing for digital signal processing and then retransmitted as an analog RF signal. The DFRM provides a time delay for RF signals by storing the signal. The DFRM also changes the signal frequency in the range of plus or minus 100,000 KHz which places a doppler on the signal. The signal phase is changed in a range of 0 to 359 degrees by the DFRM.Type: GrantFiled: July 24, 2007Date of Patent: September 7, 2010Assignee: The United States of America as represented by the Secretary of the NavyInventor: Roger Dean Durtschi

Publication number: 20100201560Abstract: A radar detection system for use with a motorcycle includes a main console that includes a single I/O interface, a detector and a controller that transmits an alert signal upon the detection of a radar or laser by the detector. The radar detection system also includes a visual alert that receives the alert signal from the main console, and a display which provides a visual display of the alert signal, with the visual alert being mounted to a portion of a motorcycle. The radar detection system further includes a wiring harness having a plurality of I/O interfaces, including a first I/O interface that is removably coupled to the single I/O interface of the main console, and a second I/O interface that is removably coupled to the visual alert.Type: ApplicationFiled: February 12, 2009Publication date: August 12, 2010Inventors: Wayne Chen, Adam Gold

Patent number: 7773025Abstract: A method and system for remotely affecting electronics within a conductive enclosure are disclosed. The method can comprise transmitting electromagnetic radiation of two different frequencies to the enclosure. The two different frequencies can be selected such that they penetrate the enclosure and therein form electromagnetic radiation of a third frequency that resonates within the enclosure. The third frequency can interact with the electronics, such as to disrupt operation thereof.Type: GrantFiled: January 30, 2008Date of Patent: August 10, 2010Assignee: The Boeing CompanyInventors: Sandor Holly, Steven B.

Patent number: 7737883Abstract: The method generally relates to the field of computer software particularly to an improved method of providing aircrew decision aids for use in determining the optimum placement of an Electronic Attack (EA) aircraft. The core of the method is a software program that will dynamically provide the EA flight crew situational awareness regarding a threat emitter's coverage relative to the position of the EA aircraft and to the position of any number of protected entities (PE). The software program generates information to provide visual cues representing a Jam Acceptability Region (JAR) contour, a Jam Assessment Strobe (JAS) and text for display on a number of flexibly configurable display formats posted on display units. The JAR and JAS graphics and text will aid the EA aircrew in rapidly assessing the effectiveness of a given jamming approach.Type: GrantFiled: February 29, 2008Date of Patent: June 15, 2010Assignee: The United States of America as represented by the Secretary of the NavyInventors: James Dark, James Buscemi, Scott Burkholder

Patent number: 7728755Abstract: The system is a parallel processing jamming architecture that is designed to automatically attack and concurrently investigate multiple signals simultaneously in the radio environment. The system implements multiple wideband independent channels to allow simultaneous threat signals to be processed in parallel and jammed in real-time. The system automatically attacks a radio communication channel when the suspect radio signal surpasses a dynamic composite threshold which is internally updated using multi-channel data feedback, in real-time. The concurrent analysis with transmission allows the system to optimize the jam efficiency quickly to an unknown signal, and while determining the validity of the threat. The high throughput parallel architecture allows the intelligent jamming process to occur with rapidity and signal multiplicity.Type: GrantFiled: March 14, 2006Date of Patent: June 1, 2010Inventor: Damjan Jocic
