Airborne high frequency (HF) direction finding is difficult due to wavelengths on the order of the aircraft size resulting in inefficient apertures and limited azimuthal resolution. This research effort focuses arrays of magnetic field sensors in a s

The number of elements in a nonplanar antenna array, their respective farfield radiation patterns, the relative spacing between the elements, and the signal processing approach determine the angle-of-arrival (AOA) estimation performance for a directi

A review of current signal analysis tools show that new techniques are required for an enhanced fidelity or data integrity. Recently, the Hilbert-Huang transform (HHT) and its inherent property, the Empirical Mode Decomposition (EMD) technique, have

The Air Force Institute of Technology (AFIT) has developed an ultrawideband (UWB) random noise radar (RNR) that operates in the UHF band. The large fractional bandwidth and lack of phase coherency within the AFIT RNR necessitate an alternative to cla
