Exploiting arrays with multiple invariances using MUSIC and MODE

  title={Exploiting arrays with multiple invariances using MUSIC and MODE},
  author={A. Lee Swindlehurst and Petre Stoica and Magnus Jansson},
  journal={IEEE Trans. Signal Processing},
This paper describes several new techniques for direction of arrival (DOA) estimation using arrays composed of multiple translated and uncalibrated subarrays. The new algorithms can be thought of as generalizations of the MUSIC, Root-MUSIC, and MODE techniques originally developed for fully calibrated arrays. The advantage of these new approaches is that the DOAs can be estimated using either a simple one-dimensional (1-D) search or by rooting a polynomial, as opposed to the multidimensional… CONTINUE READING
