Abstract
This paper studies the basic design challenges associated with multirate sensor arrays. A multirate
sensor array is a sensor array in which each sensor node communicates a low-resolution measurement to a
central processing unit. The objective is to design the individual sensor nodes and the central processing
unit such that, at the end, a unified high-resolution measurement is reconstructed
A multirate sensor array can be modelled as an analysis filter bank in discrete-time. Using this model,
the design problem is reduced to solving the following two problem: (a) How to design the sensor nodes
such that the time-delay of arrival (TDOA) between the sensors can be estimated using the low-rate data
