Description: Antenna Array Diagnosis problem is formulated in compressive sensing framework using a priori information about the failure-free antenna array radiation pattern. This framework uses the linear relationship relating the difference of the far-field radiation patterns between the reference array and the antenna under test. Three sparse based recovery approaches namely the minimization of the L1, the total variation (TV) norm, and the mixed L1/lL2 norm are discussed and analyzed by performing simulations in MATLAB. Simulations were performed using antenna array of 10 x 10 WR90 waveguide at 10GHz. Thus, the results obtained complies with our objective of having faster antenna array diagnosis with small number of measurement points.
