A signal source with a wireless frequency reference. A signal loop includes an amplifier and a coupler. The magnitude of the loop gain in the signal loop is substantially equal to 1 at a steady-state amplitude of a signal at a fundamental frequency. A reference oscillator is coupled to the loop through the coupler, via a wireless link, and provides phase stabilization. The loop may include a nonlinear transmission line, to generate a comb output spectrum.

A system for firing a projectile mounted on a carrier, the decision assistance system comprising: a first simulator for simulating a navigation system of the carrier and configured to produce a precision of a solution for navigation of the carrier; a second simulator for simulating a navigation system of the projectile and configured to be initialized with the precision of the solution for navigation of the carrier and produce a precision of a solution for navigation of the projectile; and a selector configured to select or not the projectile as projectile to be fired as a function of the precision of a solution for navigation of the projectile.

The invention relates to a method of determining the relative positions of components of a munitions system, the munitions system comprising a first component (331) and at least one second component (333). The method comprises monitoring the output of a resonant circuit (305) provided on a first component (331), the resonant circuit (305) having a resonant frequency, detecting a change in the output due to a change in the resonant frequency caused by a change in the relative positions of the first component (331) and the at least one second component (333), and using the detected change to determine that the at least one second component (333) has moved relative to the first component (331).

Embodiments include active protection systems and methods for an aerial platform. An onboard system includes radar modules, detects aerial vehicles within a threat range of the aerial platform, and determines if any of the aerial vehicles are an aerial threat. The onboard system also determines an intercept vector to the aerial threat, communicates the intercept vector to an eject vehicle, and causes the eject vehicle to be ejected from the aerial platform to intercept the aerial threat. The eject vehicle includes alignment thrusters to rotate a longitudinal axis of the eject vehicle to substantially align with the intercept vector, a rocket motor to accelerate the eject vehicle along an intercept vector, divert thrusters to divert the eject vehicle in a direction substantially perpendicular to the intercept vector, and attitude control thrusters to make adjustments to the attitude of the eject vehicle.

The system and method of improving the analysis of and implementation of a combat identification (CID) server system including providing correlation reports. There are at least two forms of correlation report, namely incident report and a summation report. The summation report has two types of totals, a summary total of all interrogations, and a breakdown of totals based on the Source JU. In one example, a correlated incident would be the combination of a Lock On or Mark Point with a Weapon Release, Disengage, or Attack.

A data processing method and apparatus, the method comprising: storing, at a first memory location in a memory, a first copy of a set of data; storing, at a second memory location in a memory, a second copy of a set of data; comparing the first copy to the second copy so as to identify, within the first copy, a pointer, the pointer being located at a first data element of the first copy, the pointer specifying a second data element of the first copy; determining an offset for the identified pointer, the offset specifying a number of data elements between the first data element and the second data element; and modifying the first copy such that the pointer within the first copy specifies the second data element using only the first data element and the offset.

A method of targeting, which involves capturing a first video of a scene about a potential targeting coordinate by a first video sensor on a first aircraft; transmitting the first video and associated potential targeting coordinate by the first aircraft; receiving the first video on a first display in communication with a processor, the processor also receiving the potential targeting coordinate; selecting the potential targeting coordinate to be an actual targeting coordinate for a second aircraft in response to viewing the first video on the first display; and guiding a second aircraft toward the actual targeting coordinate; where positive identification of a target corresponding to the actual targeting coordinate is maintained from selection of the actual targeting coordinate.

The invention relates to a method for determining characteristic-curve correction factors a matrix detector that images in the infrared spectral range. A good image correction can be obtained by virtue of an area of homogeneous temperature being recorded at two different temperatures by the matrix detector, there being two images with different integration times for each temperature. A signal gradient over the integration time is established for each of the pixels from the four pixel values at the two temperatures in each case and the gain being established from the difference of the signal gradients and characteristic-curve correction factors for the gain being stored.

A command control system includes an interception predicting section and an assigning section. The interception predicting section calculates a predicted intercept point of a target to be shot down and a guided missile to shoot down the target. The assigning section acquires first weather data of the predicted intercept point, and generates a launching instruction based on the first weather data so as to launch one of a first guided missile and a second guided missile as the guided missile. A method by which the first guided missile detects the target and a method by which the second guided missile detects the target are different.
