Coprime arrays and samplers for space-time adaptive processing

ICASSP 2015accepted

This paper extends the use of coprime arrays and samplers for the case of moving sources. Space-time adaptive processing (STAP) plays an important role in estimating direction-of-arrivals (DOAs) and radial velocities of emitting sources. However, the detection performance is fundamentally limited by…

Multidimensional Ramanujan-sum expansions on nonseparable lattices

Palghat P. Vaidyanathan

ICASSP 2015accepted

It is well-known that the Ramanujan-sum c <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">q</sub> (n) has applications in the analysis of periodicity in sequences. Recently the author developed a new type of Ramanujan-sum representation especially suite…
