Extended model of raw data signals for space-time adaptive processing and moving target indicators
conference paper
This paper presents a multi-channel synthetic aperture radar (SAR) signal model. Its purpose is to study nonstationary raw SAR signals in moving target indication (MTI) systems. This is opposed to the traditional approach in which only stationary (harmonic) signals are considered. The principal difference is that the autocorrelation function of a non-stationary signal is much sharper than the autocorrelation of a harmonic one. It will be demonstrated that this can play a significant role in the space-time adaptive processing (STAP) yielding easier and faster algorithms.
