Waveform diversity & knowledge based systems

Abstract

Waveform diversity is an emerging technology that has dramatically altered the development of futuristic radar systems, as has knowledge based processing and control. With increasing numbers of radio frequency sensors and communications systems, battlefield scenarios have become more complex and continuously redefined. Our challenge will be to effectively use this technology to enhance overall performance of advanced radar systems operating within available spectrum in these battlefield environments. Technologies essential to this goal include cognition and knowledge based systems for waveform generation timing and control, and intelligent radar signal/data processing for detection, parameter estimation and track processing. Cognition is defined as the act or process of knowing, including both awareness and judgment. Awareness of the dynamically changing spectral environment and judgment for the selection of optimal waveform parameters and sensor placement will enable dramatically improved performance for target surveillance/reconnaissance in addition to enhanced interference mitigation. A confluence of factors and technologies now makes waveform diverse knowledge based systems a logical and affordable alternative to classically designed radars.
