Abstract: Systems and methods for detecting and estimating parameters for a phase-modulated signal in a continuous manner with near-optimal performance. The methods generate these estimates using streaming (or on-the-fly) calculations and so are suitable for hardware-based implementation. These estimates can be used as part of standard pulse descriptor words for radar and other pulsed or continuous signals that are reported by an electronic warfare receiver to a processing and display system. Also, the methods can be computed using sub-sampling methods in order to reduce overall computations.

Abstract: A method, apparatus, and system for counting events. a set of quantum registers is reset. A Hadamard operator is applied to the set of quantum registers. A quantum instruction is executed on the set of quantum registers, wherein the quantum instruction incorporates a function for an event vector comprising events identified by bits. The Hadamard operator is applied to the set of quantum registers after executing the quantum instruction. The set of quantum registers is measured to form a measurement of the set of quantum registers. An approximate count of the events is determined using the measurement of the set of quantum registers.

Abstract: A computer-implemented method for processing radar information comprises receiving synthetic aperture radar (SAR) data that specifics a sequence of radar acquisitions of a target area taken over a particular acquisition time. The method comprises forming a plurality of sub-aperture images, wherein each sub-aperture image is associated with radar acquisitions of the target area taken over a particular interval of the acquisition time. The method further comprises determining, based on the plurality of sub-aperture images, velocities associated with one or more target objects moving within the target area; and generating an image associated with the SAR data that depicts the one or more target objects and the velocities associated with one or more target objects.

Abstract: Systems, methods, and apparatus for processing a signal using a non-uniform antenna array are disclosed. In one aspect, a receiver apparatus for processing high frequency signals is provided. The receiver apparatus may comprise an antenna array including a plurality of antenna elements. The plurality of antenna elements may include a first antenna element and a remainder of the plurality of antenna elements. The remainder of the plurality of antenna elements may be uniformly spaced apart from one another by a first distance and arranged in a substantially linear orientation. The remainder of the plurality of antenna elements may include a second antenna element spaced apart from the first antenna element by a second distance. The second distance may be different than the first distance.

Abstract: A method and apparatus for generating a frequency comb. A sine wave comprising samples is generated at a selected sampling rate and a selected increment corresponding to a number of samples for a period of the sine wave using a lookup table or a CORDIC algorithm. The sine wave is processed by a universal differential equation to generate the frequency comb. Characteristics of the frequency comb generated from the sine wave are controlled by changing the sampling rate and the increment.

Abstract: Systems and methods for tracking swarms of flying objects for collision avoidance using area-scanning optical systems. Images of the volume of space forward of an aircraft in flight are captured using one or more cameras and then the images are processed to determine whether the image data indicates the presence of a swarm. The camera-based collision avoidance system is configured to detect and angularly track small objects flying in a swarm at sufficiently far ranges to cue or alert the flight control system onboard an autonomous or piloted aircraft to avoid the swarm. A swarm angle tracking algorithm is used to recognize swarms of flying objects that move in unison in a certain direction by detecting a consistent characteristic of the pixel values in captured images which is indicative of swarm motion.

Abstract: Systems and methods for rapidly finding detectable signals within the field-of-view of a phased array antenna. The transmit beam pattern is modified over time to increase signal spatial search performance over typical time-delay steering by producing a coarse-to-fine angular beam pattern with a tree-based approach to signal detection. A tree-based beam search is employed to select a beam having a narrower beamwidth for transmission at an angle from boresight that lies in an angular space where a signal has been previously detected.

Abstract: A system and a method that enable two or more dispersed platforms to simultaneously use respective frequency-modulated continuous-wave radar systems in a typical radar application such as synthetic-aperture radar for terrain mapping, moving-target indicator radar to track targets on the ground and air-to-air tracking of other aircraft. The systems use the same RF spectrum in their operation and also communicate through their respective radar systems while simultaneously reducing their interplatform interference through the use of both filters and coded waveforms.

Abstract: Efficient and low-latency cueing means for initiating and updating a process of signal detection and separation in a wideband receiver. The method uses an array of IIR filters that feed an inverted state tree. The inverted state tree provides the directions for separating, detecting, and tracking multiple simultaneous signals that are being received. These signals could be either radar or communications signals and are of widely differing frequencies, bandwidths, and other characteristics. The directions are sent by the cueing system to a set of tunable tracking filters and continuously updated so that the set of tracking filters produce noise-reduced, separated signals on their outputs representing the various simultaneous incoming signals.
