Joint angle-frequency estimation using multi-resolution ESPRIT
نویسندگان
چکیده
Multi-resolution ESPRIT is an extension of the ESPRIT direction nding algorithm to antenna arrays with multiple baselines. A short (half wavelength) baseline is necessary to avoid aliasing, a long baseline is preferred for accuracy. The MR-ESPRIT algorithm allows to combine both estimates. The same algorithm can be used for multi-resolution frequency estimation, by combining two diierent sampling frequencies. We show how this can be used to construct a joint angle-frequency estimator.

Joint Angle and Frequency Estimation Using Multiple-Delay Output Based on ESPRIT
Antenna array has been used in many fields such as radar, sonar, electron reconnaissance and seismic data processing. The direction-of-arrival(DOA-) estimation of signals impinging on an array of sensors is a fundamental problem in array processing [1–5]. Angle estimation and frequency estimation [6, 7] are two key problems in the signal processing field. The problem of joint DOA and frequency ...
