Decentralized high‐resolution direction finding in partly calibrated arrays

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 communication bottlenecks system inflexibility. Here, decentralized designed, where each sensor only communicates locally their neighboring sensors. Based this mode, corresponding direction-finding approach proposed sequential that process one by one, corresponds signal processing sensor. Simulations verify method achieves decentralization minor cost estimation accuracy.
