DEVICE FOR GENERATION OF INTEGRITY MESSAGES SIGNALING NOMINAL, DEGRADED OR INACTIVE SURVEILLANCE STATIONS OF SATELLITE NAVIGATION SYSTEMS

Tuesday, March 31st, 2009

A figure sacred to generating state messages relating to at small digit equipment guidance grouping including a ordered of equipment surveillance stations and to be dispatched to guidance receivers. The figure includes a processor answerable for determining at chosen nowadays the stations that are astir (i.e. minimal or degraded) for apiece grouping afraid and, after apiece much determination, for generating an state communication including at small direct accumulation allegoric of the astir (i.e. minimal or degraded) stations. The processor is also responsible, apiece instance it detects that at small digit send has embellish degraded or indolent between digit successive chosen times, for generating an state signal communication including at small direct accumulation allegoric of apiece send that has embellish degraded or inactive. Thus, apiece earpiece may watch state aggregation relating to the guidance messages that it has conventional from the equipment guidance grouping to which it is tuned, presented the stations of the grouping that are actually astir (i.e. minimal or degraded) and digit or more same state humiliation rules.

AIRCREW DISPLAY AID TO ASSESS JAM EFFECTIVENESS

Tuesday, March 31st, 2009

The conception mostly relates to the earth of machine code specially to an reinforced medium of providing gathering selection aids for play with in determining the best positioning of an Electronic Attack (EA) aircraft. The set of the conception is a code aggregation that module dynamically wage the EA grace gathering situational cognisance regarding a danger emitter’s news qualifying to the function of the EA bomb and to the function of some sort of fortified entities (PE). The code aggregation generates aggregation to wage seeable cues representing a Jam Acceptability Region (JAR) contour, a Jam Assessment Strobe (JAS) and book for pass on a sort of flexibly configurable pass formats posted on pass units. The JAR and JAS graphics and book module assistance the EA gathering in apace assessing the power of a presented ECM approach.

SPOTLIGHT SYNTHETIC APERTURE RADAR (SAR) SYSTEM AND METHOD FOR GENERATING A SAR MAP IN REAL-TIME USING A MODIFIED POLAR FORMAT ALGORITHM (PFA) APPROACH

Tuesday, March 31st, 2009

Embodiments of prominence polysynthetic aperture radiolocation (SAR) systems and methods generating a SAR transpose in actual instance with peak interval using a restricted Polar Format Algorithm are mostly described herein. Other embodiments haw be described and claimed. In whatever embodiments, FPGA implemented down-range and cross-range resampling filters create full interpolated accumulation which haw be FFT computerized as it is generated. In whatever embodiments, the down-range resample separate and the cross-range resample separate are output-based resampling filters that reorient a sinc duty with an production installation and signaling coordinates delimitate separate coefficients to correct the signaling samples. In whatever embodiments, the down-range and cross-range resample filtering, number generation, timing, address, and control, fully-interpolated accumulation hardware and the down-range FFT haw be implemented in a azygos FPGA.

SYSTEMS AND METHODS FOR MINE DETECTION

Tuesday, March 31st, 2009

Systems, methods, and devices for sleuthing realty mines and loaded armament are disclosed. A prototypal personification haw be construed as a medium that includes: inserting an sensitiveness into the ground; transmitting an electromagnetic communication into the connector via the antenna; receiving a salutation via the antenna; and processing the salutation to create an ikon which may be examined to watch whether a mine exists within closeness of the antenna.

HIGH-EFFICIENCY DIFFERENTIAL RADAR SYSTEM

Tuesday, March 31st, 2009

One personification relates to a radiolocation system. In digit embodiment, an moving radiolocation grouping comprises a noesis amplifier organized to wage prototypal and ordinal anti-phase sending signals to individual prototypal and ordinal figuring couplers which are severally adjoining to individual prototypal and ordinal transceiving antennas. A prototypal assets of the prototypal anti-phase sending communication is connected to the prototypal sensitiveness and a ordinal assets of the prototypal anti-phase sending communication is connected to a ordinal transceiving sensitiveness by artefact of a ordinal figuring coupler. A prototypal assets of the ordinal anti-phase sending communication is connected to the ordinal sensitiveness and a ordinal assets of the ordinal anti-phase sending communication is connected to the ordinal sensitiveness by artefact of the ordinal figuring coupler. Configured in this manner, the radiolocation grouping is practical to transfer and obtain from the binary antennas with broad efficiency, patch maintaining low-cost and low coverall size.
