The problem of high-resolution direction finding is considered using a distributed array network with position errors, called partly calibrated array. These errors are common in practice, and significantly affect high angular resolution. Existing calibration methods rely on centralized data transmission, which requires all the measurements to be transmitted computation center. This mode leads c...
