  • An investigation of space-time clutter spectrum for airborne sparse array applications is given in both theory and simulation, and shown that both the rank and the spectrum of clutter covariance matrix are dependent on the sparse configuration as well as the number of temporal samples. The analysis finds that if the total aperture is unchanged and the number of half-wavelength included in any interelement spacing is lower than the number of temporal pulses, the rank of clutter covariance matrix remain unchanged, no matter how many active elements are remained. The numeric results show good agreement with the proposed theorem.

Abstract: An investigation of space-time clutter spectrum for airborne sparse array applications is given in both theory and simulation, and shown that both the rank and the spectrum of clutter covariance matrix are dependent on the sparse configuration as well as the number of temporal samples. The analysis finds that if the total aperture is unchanged and the number of half-wavelength included in any interelement spacing is lower than the number of temporal pulses, the rank of clutter covariance matrix remain unchanged, no matter how many active elements are remained. The numeric results show good agreement with the proposed theorem.
