A new calibration method developed for millimeter wave sparse arrays is presented. The method estimates a calibration matrix to compensate for unequal gain and phase responses, and the small errors in element positions simultaneously. Firstly, the data collections are done by placing two pilot sources in different near-field positions. Then taking diagonal sensor gain/phase perturbation matrix and...
This paper presents a channelized jamming reconnaissance receiver, and analyzed false response, amplitude response and temperature drift, which influence the performance of channelized receiver. For the sake of interchangeableness, we divided the receiver into RF assembly and IF assembly, then compensated each assembly independently and estimated system error. At last, we tested the receiver under...
