Toward the Development of Radar Scene Analyzer for Cognitive Radar

Overview of frequency diverse array in radar and navigation applications

“…Cognitive radar is considered as an intelligent active sensing system that utilises adaptive radar waveforms and machine learning techniques to achieve improved performance for radar tasks such as target recognition, sensor scheduling and scene analysis [93–96]. In [97], Haykin formalised the notion of cognitive radar to be a technological solution for performance optimisation in resource‐constrained and interference‐limited environments.…”

Multi-Parameter Estimation in Compound Gaussian Clutter by Variational Bayesian

“…By grouping the terms independent of u as a constant, (2) can be re-written as F (y, u, θ) = ∫ q(u) log q(u) p(u) du + const. (4) wherep (u) = Z −1 e ⟨ log p(y,u,θ) ⟩ q(θ) (5) is referred as the VB-marginal and Z is the normalizing term that ensuresp(u) is a density function.…”

“…For example, in Bayesian target tracking [1], [2], [3], the posterior probability distribution of the target is calculated based upon a prior distribution on the states of targets and the likelihood function that characterizes the information in radar measurements. In cognitive radar research (see e.g.…”

Empirical mode decomposition facilitating Bayesian Target Tracking for Cognitive Radar

“…Bu genel tanımların yanı sıra, özel olarak hedefin n anında r'inci, n − 1 anında ise q'uncu çözünürlük hücresinde olma olaylarını da sırasıyla ξ r n ve ξ q n−1 ile temsil edelim. n anında ölçülen spektral radar verisini de uygun boyutlu d n vektörü ile simgelersek, [3]'te ayrıntılı bir biçimde ilk kez formüle edildigi üzere, ROÇ'un BHT'ye saglaması gereken istatistiksel bilgilerşöyledir:…”
