Abstract

In the presented work, the urgent problem of detecting low-flying radar targets is touched upon. The problem has been known for a long time, but only now, there are computing capacities for testing algorithms for measuring angular coordinates. In this regard, the study of the ESPRIT super-resolution algorithm is carried out, and the error of measuring angular coordinates is estimated depending on the height of the surface irregularities. The presence and magnitude of this error are directly related to an increase in the power of the diffuse component of the signal, which in turn destroys correlations in the elements of the antenna array, on which the measurement of angular coordinates by the ESPRIT algorithm is based.
