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: 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 blind source separation (BSS) system comprises means for gathering wideband signal power spectral information without using special Fourier transform hardware/software systems and without using extremely large signal memories. The method involves taking the combined energy output of a large set of BSS filters that are operating under a blind source separation algorithm that looks for signals of interest, along with instantaneous filter characteristics such as center frequency, bandwidth and spectral response, and records a weighted spread energy into a frequency- and time-based histogram. This information can then be used to compare against the BSS signal output and signal energy which does not correspond to existing signal output is added to additional BSS signal output. This system can operate in real time, but uses long-term averaging to enhance signal detection.

Abstract: A signal processing system is provided. The signal processing system includes a transmission architecture configured to transmit first and second signals, and a receiver architecture including an antenna configured to receive the signals, and a coherent signal fusion processing device communicatively coupled to the antenna. The processing device is configured to generate a broadband analog signal that contains the first and second signals, digitize the broadband analog signal, isolate first and second signals of interest, estimate, relative to a reference template, at least one of a time difference of arrival and a frequency difference of arrival for at least one of the first and second signals of interest, and determine a location of at least one of the transmission architecture and the receiver architecture based on the estimated at least one of a time difference of arrival and a frequency difference of arrival.

Abstract: A method for training a neural network to be configured to filter a multipath corrupted signal is provided. The method includes receiving, at the neural network, real or simulated multipath corrupted signal data, and training the neural network on the multipath corrupted signal data using a complex iterated least square thresholding algorithm (CILST) capable of processing both real and complex signals.

Abstract: A device includes a bus interface to couple to a shared bus of a sensor network. The device also includes a sensor interface to couple to a sensor of the sensor network. The device further includes a gated pulse width modulation circuit coupled to the bus interface and to the sensor interface. The gated pulse width modulation circuit is configured to transmit, during a time slot determined based on a timing signal received via the shared bus, an analog pulse width modulated representation of a signal received from the sensor.
