Total Variation Compressed Sensing as Applied in Array Antenna Diagnosis

A new method for array antenna diagnosis using total variation compressed sensing is proposed. The effects of failure rate and failure location on the radiation pattern of the array antenna are verified by simulation, the simulation prove that the sidelobe level is mainly affected. The proposed diagnosis algorithm based on total variation compressed sensing is analyzed theoretically, the gradient of the excitation is considered as an optimization objective. Some numerical simulations verify the accuracy and efficiency of this diagnosis algorithm.
