Comparison of the Effectiveness of the MUSIC and ESPRIT Superresolution Algorithms

Abstract

In radar, it is of great importance to distinguish targets separated by a small angular distance, for example, two close-flying aircraft located at a great distance from the radar station or distinguishing a low-flying target and its antipode, arising due to signal reflection from the underlying surface. This article compares the efficiency of the MUSIC and ESPRIT superresolution algorithms for the problem of distinguishing two targets separated by a small angular distance. According to the simulation results, the ESPRIT algorithm is faster than MUSIC for the same antenna array and signal parameters, ESPRIT has a smaller RMS deviation for the same parameters, which suggests that the ESPRIT superresolution algorithm is more efficient.
