Abstract :
High-resolution methods for passive array processing have proved to be very efficient in increasing resolving power. The theory developed up to now is essentially narrowband, but it has been proved, using the Cramer-Rao bound, that it is possible to increase the resolving power by using a broad frequency bandwidth. A method that allows the solution to be computed analytically for a linear array with equally spaced sensors is presented. Results that show the improvement are reported
