| 20080246648 | METHODS FOR RAPID TARGET ACQUISITIONS IN RANGE MEASUREMENT SYSTEMS - A method for acquiring targets within a search area using an electronic device is disclosed. The method involves partitioning a first acquisition time period into a plurality of range gates, simultaneously positioning one or more of the range gates within the search area during a search mode, and transmitting an energy pulse train. Upon receipt of a reflection of the transmitted pulse train, the method records a signal level of the reflected energy pulse train within the first acquisition time period. Based on the recorded signal level, the method advances one or more of the range gates by a prescribed outbound movement increment until the signal level within at least one of the range gates is above a prescribed acquisition signal level threshold. | 10-09-2008 |
| 20090174594 | HIGH FREQUENCY RADAR ALTIMETER - In one aspect, a method of radar altimeter operation, the altimeter including a high frequency counter coupled to a processor is described. The method comprises providing a continuous wave to the high frequency counter upon receipt of a transmit pulse, counting the cycles of the continuous wave, discontinuing counting of the continuous wave cycles upon receipt of a return pulse, outputting a count from the high frequency counter to the processor, and operating the processor to convert the count to an altitude. | 07-09-2009 |
| 20100019949 | Processing of pulse-echo measurements signals - Pulse echo signals containing false echoes are processed by forming tracks of multiple received echoes and monitoring these tracks by a recursive filter such as a Kalman filter. A track velocity is estimated for each track, and the position of each the next echo on the track is predicted. | 01-28-2010 |
| 20100085239 | Device and method for detecting a target using a high speed sampling device - Devices and methods for detecting a target using a logic circuit for increasing the accuracy and speed at which targets can be detected in security and surveillance applications. A commercially available field programmable gate array may be used as the logic device. In one embodiment, the Multigigabit Transfer port (MGT) of the field programmable gate array is locked to an external clock. The coupling of the MGT port to an external clock increases the rate at which the received signal is sampled, without having to use the device in the oversampling mode. By doing so, the field programmable gate array is able to sample at least eight times faster than the actual transfer rate, which increases the speed and accuracy by which a target can be detected. | 04-08-2010 |
| 20120062411 | MILLIMETER AND SUB-MILLIMETER WAVE RADAR-RADIOMETRIC IMAGING - An antenna is provided that is configured to implement a combined radar and radiometric imaging method. The antenna comprises: a bearing device on which is rigidly mounted: rotating waveguide adapter which provides the output for the antenna; an electromechanical drive, the output shaft of which is defined as the main axis of rotation for the antenna and a position sensor. The antenna further comprises an antenna rotor, the rotation of which is configured to be controlled by the output shaft of the electromechanical drive of the bearing device. The antenna rotor comprises: at least one 2D diffraction grating; planar dielectric waveguide connected over a diffraction field to the 2D diffraction grating; a linear waveguide turn; and a feed adapter. | 03-15-2012 |

| 20110254726 | Systeme Radar UHF Pour Mettre en Oeuvre un Procede d'Elimination d'un Fouillis de Vegetation - A system includes a pulsed UHF radar for integrating the signal received over a given integration time. The integration time for the received signal and the size of the distance bin are defined in such a way that, taking into account the range of speeds of the targets of interest, a moving target of interest travels only a distance shorter than the size of the distance bin from one integration period to another. Furthermore, the UHF radar implements a method of forming radar blips from the received signal to form elementary blips from the signals received over the chosen integration time and to store them from one burst to another. The method also confirms that the elementary blips formed probably correspond to targets of interest and then forms, from the confirmed elementary blips, aggregate blips, the attributes of an aggregate blip depending on the attributes of the confirmed elementary blips from which the aggregate blip stems. The method also validates the aggregate blips formed, the validation of an aggregate blip depending on the distance measurement associated with this blip. The transmission of parasitic blips is reduced, brought about by the detection of echos relating to the movement of vegetation due to the action of the wind, to the tracking means. | 10-20-2011 |
| 20140028489 | TARGET TRACKING APPARATUS, STORAGE MEDIUM STORED A TARGET TRACKING PROGRAM, TARGET TRACKING SYSTEM, AND TARGET TRACKING METHOD - According to one embodiment, a target tracking apparatus acquires a first determination result by determining which combination of N-dimensional tracks is for the real target, acquires a second determination result by determining which combination of N-dimensional angular observation values is for the real target, selects the first determination result when an observation environment is an environment other than a dense environment, selects the second determination result when the observation environment is a dense environment, and calculates distance information to thereby generate an (N+1)-dimensional track for each target. | 01-30-2014 |

| 20130002472 | ACTIVE RETRODIRECTIVE ANTENNA ARRAY WITH A VIRTUAL BEACON - An active retrodirective antenna array is provisioned with a virtual beacon for use with uncooperative targets. An RF pilot signal is imposed onto an optical carrier beam and directed at a target. The scattered optical carrier beam is optically detected by a plurality of the retrodirective array nodes to extract the RF pilot signal. Each recovered RF pilot-signal is phase-conjugated with a phase reference signal, amplified and retransmitted towards the target where the RF beams add-in phase at the virtual beacon. The array may be used to complete an RF communication link with the target, to transfer microwave power from orbiting solar power stations to a target or as a directed energy weapon to prosecute the target. | 01-03-2013 |
