Coprime sampling has, in the past, been used for signal processing applications such as range and doppler improvement in radar, and for identifying sinusoids in noise. This paper considers a coprime pair of samplers in space or time from the point of view of the difference coarray, which is key to the increased freedom available for processing with such arrays. First, two uniform linear arrays with N and M elements in space are considered. With the interelement spacings in the two arrays given… CONTINUE READING
