Properties

The MUSIC algorithm is one of the high-resolution techniques for DOA estimation. It is capable of reliably resolving targets with angular separation of as low as 1° from severely degraded received signals with very few spurious peaks in the pseudo-spectrum. Since MUSIC computes the pseudo-spectrum of the received signal, it cannot be used to estimate the power of the signal sources. For power estimation, DBF or Capon can be used in conjunction with MUSIC. By increasing the number of snapshots used for spectrum estimation, the ability of MUSIC to separate multiple targets can be improved.

Despite the high performance, MUSIC requires prior knowledge of the size of the signal subspace. It also depends on eigen-decomposition which requires high computational complexity. Root-MUSIC
