Abstract: A method and system for Kalman-Filtering in geolocation is provided. One aspect of the disclosure provides using an extreme geo program/method to converge on the location of an emitter, using a correlation function inherent in a Correlation Interferometry Geolocation (CIGL) program, and using Kalman filtering to find a peak correlation surface for an array.

Abstract: Techniques are disclosed for partial band signal reconstruction. A partial band signal reconstruction circuit includes a zero generator, an analysis filter, and a synthesis filter. The zero generator is configured to generate a zero-value channel (i.e., a signal of all zeros). The analysis filter is configured to convert a wideband time-domain signal into K narrow-band channels, and to select at least R of the K frequency-domain subchannels for synthesis. The synthesis filter is configured to receive the at least R subchannels from the analysis filter and the zero or more zero-value channels from the zero generator and convert the at least R subchannels and the zero-value channels (a total of P channels) into a time-domain signal. The values of K and P are related by a constraint that constrains one or more parameters of the analysis filter and the synthesis filter.
