MIMO Radar Ambiguity Properties and Optimization Using Frequency-Hopping Waveforms [PDF]
, 2008 The concept of multiple-input multiple-output (MIMO) radars has drawn considerable attention recently. Unlike the traditional single-input multiple-output (SIMO) radar which emits coherent waveforms to form a focused beam, the MIMO radar can transmit ...

Space-variant ambiguity function processor [PDF]
Applied Optics, 1979 The ambiguity function that results from the space-variant optical processing of nonlinear coded waveforms is analyzed. The space-variant signal processor considered is realized by coordinate transformations. Specifically we consider x = lnt, which results in a Mellin transform-based Doppler-invariant signal processor.

Properties of the MIMO radar ambiguity function [PDF]
, 2008 MIMO (multiple-input multiple-output) radar is an emerging technology which has drawn considerable attention. Unlike the traditional SIMO (single-input multiple-output) radar, which transmits scaled versions of a single waveform in the antenna elements ...

Ordering ambiguity revisited via position dependent mass pseudo-momentum operators [PDF]
, 2006 Ordering ambiguity associated with the von Roos position dependent mass (PDM) Hamiltonian is considered. An affine locally scaled first order differential introduced, in Eq.(9), as a PDM-pseudo-momentum operator.

Ambiguity function and accuracy of the hyperbolic chirp: comparison with the linear chirp [PDF]
, 2017 In this paper, we derive the Ambiguity Function (AF) of a narrowband and a wideband hyperbolic chirp. We calculate the second derivatives of the squared amplitude of the narrowband Complex Ambiguity Function (CAF) and use them to calculate the Fisher ...
