Slow-Time MIMO Waveform Design Using Pulse-Agile-Phase-Coding for Range Ambiguity Mitigation

Remote Sensing, 2023
This paper proposed a Pulse-Agile-Phase-Coding slow-time MIMO (PAPC-st-MIMO) waveform, where the phase-coded signal is utilized as the intra-pulse modulation of the slow-time MIMO waveform.

Range‐ambiguity suppression for noise radar in cluttered environment via sparse recovery

Electronics Letters, 2021
Range ambiguity suppression is a significant problem in traditional pulse‐Doppler radar systems, especially when the pulse repetition frequency is set high to avoid Doppler ambiguity. One possible way to deal with such problem is to apply the noise radar

Ambiguity and Social Interaction [PDF]

, 2005
We present a non-technical account of ambiguity in strategic games and show how it may be applied to economics and social sciences. Optimistic and pessimistic responses to ambiguity are formally modelled.

Testing dynamic consistency and consequentialism under ambiguity [PDF]

, 2020
Accounting for ambiguity aversion in dynamic decisions generally implies that either dynamic consistency or consequentialism must be given up. To gain insight into which of these principles better describes people's preferences, we tested them using a ...

Range-Angle Localization of Targets With Planar Frequency Diverse Subaperturing MIMO Radar

IEEE Access, 2018
Target localization utilizing frequency diverse array (FDA) has received much attention in recent years. In this paper, we propose a tensor subspace-based multiple-target 3-D localization method with planar frequency diverse subaperturing multiple-input ...

A Robust Coarse-to-Fine Ambiguity Resolution Algorithm for Moving Target Tracking Using Time-Division Multi-PRF Multiframe Bistatic Radars

Remote Sensing
The bistatic radar has been widely applied in moving target detection and tracking due to its unique bistatic perspective, low power, and good concealment.

Ambiguity, ambiguity aversion and the coverage of uncertain risks : the case of the insurer [PDF]

, 2011
Ambiguity aversion is defined as an aversion to any mean-preserving spread in the probability space. Using the Smooth Ambiguity Model proposed by Klibanoff, Marinacci and Mukerji (2005), we show that ambiguity aversion results in a reduction in the ...

In-Orbit Operational Parameter Calculation and Performance Optimization in KOMPSAT-6 Synthetic Aperture Radar

Remote Sensing, 2021
A new method to design in-orbit synthetic aperture radar operational parameters has been implemented for the Korean Multi-purpose Satellite 6 mission. The implemented method optimizes the pulse repetition frequency when a satellite altitude changes from ...

Ambiguity and communication [PDF]

, 2009
The ambiguity of a nondeterministic finite automaton (NFA) N for input size n is the maximal number of accepting computations of N for an input of size n.
