Abstract :
Arrays of randomly positioned sensors have several advantages, including a relative independence of DI on frequency and narrow beams without spatial aliasing. They have corresponding disadvantages in that there is many beams are required to cover all angles. Certain interference cancellation techniques are described that can compensate for the lack of shading. These cancellation techniques explicitly account for the vertical multipath structure of the interference waveform.
