Abstract :
A wide band frequency scanning array is implemented for measuring the frequency and DOA of an RF signal. A novel low-profile type of antenna, TaCuRaS has been developed to be utilized in the array. A look-up table comprising the array response is prepared for the estimation procedure. Despite of discrete data, the approach of 2-D inverse interpolation associated with the error norm minimization yields a considerable resolution in the estimates.
