CONVOLUTIONAL DIGITAL RADIO FREQUENCY MEMORY (DRFM) JAMMING
A technique of jamming a victim radar includes digitizing an incident waveform received from the victim radar and convolving the digitized waveform with contents of a range trace memory. The range trace memory stores a sequence of impulses, which, when convolved with the digitized waveform, creates a corresponding sequence of delayed versions of the digitized waveform, one for each impulse in the sequence, and adds together the delayed versions to produce a single output signal. The output signal is then converted to analog form and transmitted back toward the victim radar.

A technique of jamming a victim radar includes digitizing an incident waveform received from the victim radar and convolving the digitized waveform with contents of a range trace memory. The range trace memory stores a sequence of impulses, which, when convolved with the digitized waveform, creates a corresponding sequence of delayed versions of the digitized waveform, one for each impulse in the sequence, and adds together the delayed versions to produce a single output signal. The output signal is then converted to analog form and transmitted back toward the victim radar.

Providing a load from a motor to inhibit further rotation of a propeller of an aerial vehicle while in flight
A technique for operating an aerial vehicle involves enabling a vertical takeoff and landing (VTOL) propeller of the aerial vehicle to rotate freely. The VTOL propeller is coupled with a VTOL motor (e.g., a 3-phase brushless DC motor). The technique further involves detecting when the VTOL propeller rotates to a predefined position relative to a direction of flight for the aerial vehicle (e.g., when blades of the VTOL propeller extend along an axis that is parallel to the direction of flight). The technique further involves, in response to detecting that the VTOL propeller has rotated to the predefined position, providing a load from the VTOL motor that inhibits further rotation of the VTOL propeller. Accordingly, while the aerial vehicle is in fixed wing horizontal flight, the controller is able to align the VTOL propeller in the direction of horizontal flight to minimize drag from the VTOL propeller.

Safeguarding equipment based on detection of reduced cyclical pump performance
A technique of safeguarding equipment involves deriving a pressure pulse amplitude based on operation of a pump of the equipment, and performing a comparison operation that compares the pressure pulse amplitude value to a predefined threshold. The technique further involves performing, in response to a result of the comparison operation indicating that the pressure pulse amplitude value has fallen below the predefined threshold, a remedial activity to prevent damage to the equipment or to prevent endangerment to persons affected by the failure of the equipment. For example, in the case of an unmanned aerial vehicle (UAV), the remedial action may be to transit the UAV from a densely populated area to a rural area where landing may be possible without injuring persons or damaging the UAV.

MANEUVERABILITY INVOLVING A FIXED-WING AIRCRAFT AND AN AERIAL VEHICLE HAVING VERTICAL TAKEOFF AND LANDING CAPABILITIES
Techniques involve releasing and/or capturing a fixed-wing aircraft (22) using an aerial vehicle (24) with VTOL capabilities while the fixed-wing aircraft (22) is in flight. For example, the vehicle (24) may take off vertically while carrying the fixed-wing aircraft (22) and then fly horizontally before releasing the fixed-wing aircraft (24). Upon release, the fixed-wing aircraft flies independently to perform a mission. After the fixed-wing aircraft has completed its mission, the vehicle may capture the fixed-wing aircraft while both are in flight, and then land together vertically. Such operation enables the fixed-wing aircraft to vertically take off and/or land while avoiding certain drawbacks associated with a conventional VTOL kit such as being burdened by weight and drag from the VTOL kit's rotors/propellers, mounting hardware, etc. during a mission which otherwise would limit the fixed-wing aircraft's maximum airspeed, ceiling, payload capacity, endurance, and so on.
