Abstract
The radar seeker of missile under consideration uses monopulse techniques measure the target angular displacements. However, when multiple unresolved targets are present, the angular information cannot be extracted correctly. A novel method is proposed which implements a long coherent integration and the fractional Fourier transform to resolve such targets instead of the conventional Fourier transform. The accuracy of DOA measurements is guaranteed as shown in the simulation results
