A system and method for nulling or suppressing interfering signals directed toward moving platforms based, at least in part, on dynamic motion data of the moveable platform is provided. The system may be an interference nulling system carried by a moveable platform and may include an antenna array including two or more antenna elements that generates at least one initial steerable null radiation pattern, dynamic motion data logic that determines dynamic motion data of the moveable platform; and update logic that updates the at least one initial steerable null radiation pattern based, at least in part, on the dynamic motion data. The at least one updated steerable null radiation pattern is directed toward a direction from which interfering signals are being transmitted from an interfering signal source.

System and method for nulling or suppressing interfering signals in dynamic conditions

A guided projectile including a precision guidance munition assembly utilizes at least one maneuver envelope to optimally control movement of at least one canard to steer the guided projectile during flight. The maneuver envelopes optimize movements of the at least one canard that effectuate movement in either the range direction or the cross-range direction, or both. The maneuver envelope enables optimal timing such that maneuvering in one direction does not come at the expense of maneuver authority in the other direction.

Method for controlling a projectile with maneuver envelopes

The system and method of projectile flight management using a combination of radio frequency orthogonal interferometry for the long range navigation and guidance of one or more projectiles and a short range navigation and guidance system to provide for more accurate targeting.

Orthogonal interferometry artillery guidance and navigation

A system and method for state estimation in spinning projectiles is provided. The state estimation is based, at least in part, on magnetic sensor data, angular velocity data, and correction terms applied to the magnetic sensor data and the angular velocity data. The system and method for state estimation in spinning projectiles estimates roll angles and roll rates of the spinning projectiles. The roll angle and roll rate estimates allow steering commands to be applied to steer the spinning projectiles in the proper direction.

State estimation

This invention describes a method for operating a weapon targeting system comprising the steps of using a laser to fire a single pulse at a target to obtain a reflected laser pulse; detecting the reflected laser pulse as a signal by a SWIR focal plane; detecting background illumination by using the SWIR focal plane; scene clutter filter and using optical filtering if it is necessary to suppress background illumination.

Laser detection and image fusion system and method

A laser range finder (LRF) and an automated method for determining a return laser signal associated with a target thereof are disclosed. In one example embodiment, the LRF includes a laser beam emitter to emit a laser beam towards a target. Further, the LRF includes a receiver circuit to receive multiple return laser signals reflected from objects including the target and to determine an amplitude of each of the multiple return laser signals. Furthermore, the LRF includes a processor coupled to the receiver circuit to compare the amplitude of each of the multiple return laser signals with a range varying threshold that accounts for range and atmospheric losses and to determine one of the multiple return laser signals as being associated with the target based on the comparison.

Determining a return laser signal associated with a target in laser range finders

An optical bench assembly is disclosed. In one embodiment, the optical bench assembly includes a housing and a cantilever optical bench for holding optical components. Further, the cantilever optical bench includes a front flange coupled to the housing and an optical bench attached to the front flange such that the optical bench is not susceptible to movements of the housing due to varying ambient conditions and resulting loads.
