The Development of Radar and Radar Countermeasure

Comprehensive design of a distributed intelligent unmanned shipborne radar system

“…According to different usage areas, intelligent unmanned systems can be divided into intelligent unmanned aerial vehicle systems, ground intelligent unmanned systems, and maritime intelligent unmanned systems. This article mainly discusses the intelligent unmanned combat system at sea [14]. Starting from practical needs, based on the latest progress in communication technology, combined with network technology, control technology, and radar technology, a distributed remote control shipborne radar system is designed, focusing on solving the problem of unmanned shipborne radar and achieving unmanned and intelligent remote control of shipborne radar.…”

Detecting Changes in Strategy of a Cognitive Radar: a Stochastic Revealed Preference Framework

“…based on the constrained utility maximizing behaviour in (23). The probe vector α t = [1, 0.8, 1.8] T and budget constraint b t = 1.67 were kept the same for all 22 observations, and the aforementioned values were obtained as random samples, each drawn from α t ∼ Unif[0.5, 2] 3 and b ∼ Unif [1,3] as in [5], [42]. However, since the utility is ordinal, by virtue of Afriat's theorem, b t can be chosen as 1 without loss of generality, and hence need not be known to our side in order to make revealed preference inferences [5].…”

“…This innovation not only improved the performance of radar systems but also expanded the horizons of what radar technology can achieve in various domains, ultimately enhancing its utility and impact [2]. The emergence of cognitive radar technology has led to a surge in research within the fields of Electronic Countermeasures (ECM) [3] and Electronic Counter-Countermeasures (ECCM) [4], wherein adversaries employ ECM/ECCM strategies to counteract the capabilities cognitive radar. In this paper, we study an ECM problem of detecting changes in strategy (changepoint detection problem) of an adversarial cognitive radar.…”
