AbstructThe high-order ambiguity function (HAP) is a nonlinear operator designed to detect, estimate, and classify complex signals whose phase is a polynomial function of time. The HAF algorithm, introduced by Peleg and Porat, estimates the phase parameters of polynomial-phase signals measured in noise. The purpose of this correspondence is to analyze the(More)
In a recent paper, the authors have explored the use of novel concentration sensors for detecting and localizing vapor-emitting sources. As was shown there, an array of sensors (at least five) is needed for this purpose in general. In the present paper we propose to replace stationary sensors by moving sensors, thus gaining two important advantages: 1 ) A(More)
