Abstract: The present disclosure relates to an optical sensor protection system. The system may have a sensor for receiving an incoming optical signal, a passive sensing and modulation component, and an active sensing and modulation subsystem. The passive sensing and modulation component is configured to sense when a first characteristic is associated with the incoming optical signal is present that adversely affects operation of the sensor, and redirects at least a portion of the incoming optical signal thereof away from the sensor to thus reduce an intensity of the incoming optical signal reaching the sensor. The sensor is located on an image plane downstream of the ISM subsystem, relative to a path of travel of the incoming optical signal. The active sensing and modulation subsystem has an active modulation component and is located upstream of the passive sensing and modulation component, relative to the path of travel of the incoming optical signal, and is also located on a conjugate image plane, and is configured to use the redirected portion of the incoming optical signal as feedback in controlling a modification of the incoming optical signal to reduce a risk of damage to the passive sensing and modulation component.

Abstract: A circuit comprises a receive processing window formation subsystem, a matched filter subsystem, a keystone interpolation subsystem, a phase modulation subsystem, and an image forming subsystem. The receive processing window formation subsystem forms, for each radar return from a scene, a receive processing window containing the radar return as an unbroken radar return. The matched filter subsystem creates a motion model for a reference point target disposed at a predetermined location within the scene, based on a set of motion compensation parameters for range and range rate, to compensate for at least some effects of fast time Doppler on the reference point target. The keystone interpolation subsystem rescales slow time information from the matched filter subsystem. A phase modulation subsystem applies phase modulations to a keystone-interpolated 2-D output array of information associated with the scene, to ensure proper registration in a range-Doppler map output of the scene.

Abstract: A method includes receiving an outgoing data stream and dividing the outgoing data stream to generate multiple electromagnetic signals in multiple channels using a first manifold. The method also includes modifying at least some of the electromagnetic signals in at least some of the channels to generate scrambled electromagnetic signals. The method further includes combining the scrambled electromagnetic signals to generate one or more outgoing scrambled combined electromagnetic signals using a second manifold. In addition, the method includes transmitting the one or more outgoing scrambled combined electromagnetic signals. The outgoing data stream may include an outgoing optical data stream, and a photonic integrated circuit may divide the outgoing optical data stream and produce scrambled optical signals. The photonic integrated circuit may be configured to handle outgoing optical data streams having different protocols and/or different data rates.

Abstract: A warning receiver can be detachably mounted on the inside of a window of a manned platform to detect RF or RF and laser threats and to provide visual or audio warnings to the human occupant. The warning receiver is fully self-contained and independent of any systems on the manned platform. In different packaging configurations, the receiver can be manually rotated to better visualize the threat and/or the receiver's human-machine interface (HMIF) can be manually rotated to better display the warnings. Although most typically used in manned aircraft the warning receiver can be used in other manned vehicles or ships.

Abstract: Optical sensors and particularly gimbaled optical sensors transmit an active signal at a given wavelength(s) and receive passive signals over a range of wavelengths and the active signal in a common aperture. The sensor includes a Tx/Rx Aperture Sharing Element (ASE) configured with a center region that couples the active signal to the telescope for transmission and an annular region that couples the passive emissions and the returned active signal to the detector. A filter wheel may be positioned behind the ASE to present separate passive and active images to the detector. These optical sensors may, for example, be used with guided munitions or autonomous vehicles.

Abstract: A bidirectional drawer system is disclosed. The bidirectional drawer system can include a frame. The bidirectional drawer system can also include first and second drawers slidably coupled to the frame. Each of the first and second drawers can be movable between a retracted position and first and second extended positions on opposite sides of the retracted position. In addition, the bidirectional drawer system can include a drawer interlock mechanism. The drawer interlock mechanism can include first and second interlock portions associated with the first and second drawers, respectively. The first interlock portion can have a cam with a cam surface, and a cam follower operable to interface with the cam surface. The second interlock portion can have a cam lock with a cam lock surface, and cam follower operable to interface with the cam lock surface. With the first and second drawers in the retracted positions, movement of the first drawer toward the first extended position can cause the cam follower of the first interlock portion to engage the cam surface and the cam follower of the second interlock portion to engage the cam lock surface thereby preventing movement of the second drawer out of the retracted position.
