Multi-dwell channel monitoring for coordinated frequency hopped systems

Abstract

Spectral environment estimation systems and methods are provided for use with frequency hopped communications systems. A spectral sensor is configured to receive input signals from a signal aperture and to perform spectral estimations on the input signals to generate a frequency domain spectral estimate. Ordinary spectral characterization circuitry is configured to receive the frequency domain spectral estimate as an input and to produce an ordinary frequency domain spectral environment estimate based on the spectral estimate. Frequency hopping translation circuitry is configured to receive the frequency domain spectral estimate from the spectral sensor as an input and to produce a de-hopped channel domain spectral estimate based on the frequency domain spectral estimate. De-hopped spectral characterization circuitry is configured to receive the de-hopped channel domain spectral estimate as an input and to produce a de-hopped channel domain spectral environment estimate based on the de-hopped spectral estimate. Spectral environment integration circuitry is configured to generate an integrated spectral environment estimate, based on the ordinary frequency domain spectral environment estimate and the de-hopped channel domain spectral environment estimate, for use by networked communications systems or devices in controlling frequency hopped communications.
