Novel Radar Waveform Optimization for a Cooperative Radar-Communications System

open access: yesIEEE Transactions on Aerospace and Electronic Systems, 2019
We develop and present a novel minimum estimation error variance waveform design method. The method optimizes the spectral shape of a unimodular radar waveform such that the performance of a joint radar-communications system that shares spectrum is ...

Similarity Classes in the Eight-Tetrahedron Longest-Edge Partition of a Regular Tetrahedron

open access: yesMathematics, 2023
A tetrahedron is called regular if its six edges are of equal length. It is clear that, for an initial regular tetrahedron R0, the iterative eight-tetrahedron longest-edge partition (8T-LE) of R0 produces an infinity sequence of tetrahedral meshes, τ0 ...

Cooperative Radar and Communications Signaling: The Estimation and Information Theory Odd Couple [PDF]

open access: yes, 2014
We investigate cooperative radar and communications signaling. While each system typically considers the other system a source of interference, by considering the radar and communications operations to be a single joint system, the performance of both ...

Communications System Performance and Design in the Presence of Radar Interference

open access: yesIEEE Transactions on Communications, 2018
Increasing demands for spectrum have necessitated the coexistence of communications and radar systems within the same band. This paper investigates how an unaltered radar system affects the performance of a communications receiver.
