“…Contact methods of earth surface and atmosphere monitoring are being actively supplemented by non-contact, remote methods. An ever-greater amount of information is supplied by lidar [1] and acoustic sensing [2], measurements in optical [3], terahertz and microwave ranges [4], radar evaluation of environmental parameters [5][6][7][8]. Information value of active monostatic radars in relation to radiophysical properties of the sounding medium is determined by their capabilities in evaluation of its backscattering matrix for each element of the sensor resolution.…”

“…However, the remaining questions were not investigated in detail. Existing research shows that (a) the change in excitation due to temperature drift lowers the probability of failure detection and increases the rate of false positives [5,15]; (b) errors in the measurement matrix also lead to low accuracy of excitation reconstruction [16].…”

This paper presents two modifications of compressive sensing (CS)-based approach applied to the near-field diagnosis of active phased arrays. CS-based antenna array diagnosis allows a significant reduction of measurement time, which is crucial for the characterization of electrically large active antenna arrays, e.g. used in synthetic aperture radar. However, practical implementation of this method is limited by two factors: first, it is sensitive to thermal instabilities of the array under test, and second, excitation reconstruction accuracy strongly depends on the accuracy of the elements of the measurement matrix. First proposed modification allows taking into account of thermal instability of the array by using an iterative ℓ1-minimization procedure. The second modification increases the accuracy of reconstruction using several simple additional measurements.
