Benefits of technology

The present invention is a system and computer program for estimating the utilization of an electromagnetic signal receiver. The system receives electromagnetic signals from the surrounding environment and creates data from them. The signals are then chronologically segregated into a plurality of dwells each with an elapsed time. The system controls the scanning of the surrounding environment and computes a plurality of utilizations by dividing each individual elapsed time by a predetermined sample interval. The system also determines a total utilization by adding the plurality of utilizations. The technical effect of this invention is to provide a more accurate and efficient way to estimate the utilization of an electromagnetic signal receiver.

Problems solved by technology

This process of estimating the utilization metric is accurate, but suffers from large delays associated with inability to control the utilization estimate update rate.

Embodiment Construction

[0016] Electronic support measure (ESM) receiver systems typically are ground based, airborne, or sea based (surface or sub-surface platforms) systems that passively detect threat signals of interest, typically radar and communication signals. An ESM system identifies, classifies, and prioritizes detected signals for display to an operator or crew. The goal is to provide the crew with a tactical picture, or “situational awareness”, of the electromagnetic environment around them, such that the crew may react and counter any threats (e.g., maneuver, apply counter measure, attack, etc.). Since signal detection is passive (only receiving), an ESM receiver cannot be detected (i.e., an operator of a threat does not know that the ESM is in operation or that the threat has been detected, identified, and possibly located, etc.).

[0017] Although there are many variations, a typical ESM receiver system 10, as seen in FIG. 1, consists of an antenna array 20, low noise preamplifier 30, antenna c...

Abstract

A system estimates the utilization of an electromagnetic signal receiver. The system includes a detection module and a processing module. The detection module receives electromagnetic signals from a surrounding environment. The electromagnetic signals are chronologically segregated into a plurality of dwells each with an elapsed time. The processing module controls the scanning of the surrounding environment. The processing module receives data about the signals from the detection module. The processing module computes a plurality of utilizations by dividing each individual elapsed time by a predetermined sample interval. The processing module further determines a total utilization by adding the plurality of utilizations.

Description

FEDERAL SPONSORSHIP [0001] The U.S. Government has a paid-up license in this invention and the right, in limited circumstances, to require the patent owner to license others on reasonable terms as provided for by the terms of Contract No. N00019-97-C-0147 awarded by the U.S. Navy.FIELD OF INVENTION [0002] The present invention relates to a system for signal processing and, more specifically, a system for estimating receiver utilization. BACKGROUND OF THE INVENTION [0003] Typically, transmitted signals are collected by a receiver and processed during predetermined time intervals called dwells. The processing of signals received during a previous dwell occurs during a subsequent dwell. An inter-dwell period exists between dwells to allow for the reconfiguration of data processing circuits and other hardware in response to the processed data of the most recent dwell. Any processing of received signals or collecting of received signals is typically halted during this inter-dwell period....
