ARMA Techniques for the location of multiple sources from linear array data

A new method is presented for resolving the directions of multiple sources whose emitted radiation is received by a linear array of sensors. A linear predictive type ARMA model is derived for the received signals where the data represents incident radiation from multiple sources plus measurement noise. The model facilitates identification of coherent sources from non-equispaced sensor data which more realistically represents the all important practical radar situation, and also accounts for multipath effects.
