This document derives approximate expressions for the Cramèr-Rao lower bounds on the variance of unbiased estimates of the parameters of a narrow-band radar model in the presence of additive white Gaussian noise as well as interference with known structure. We show that the Cramèr-Rao lower bounds with interference are comprised of the bound when the interference is not present and a term that is...
In this paper we describe a hybrid data and decision adaptive beam forming and processing strategy using a novel W-band (75–84 GHz) phased array architecture for automotive collision avoidance radars. We use the term ‘decision adaptive’ to denote the situation where the output of a tracking algorithm initializes the weight vector of the antenna array such that the main formed beam can be coarsely...
In this paper we describe a decision adaptive beam forming and processing strategy using a novel W band phased array architecture for automotive collision avoidance Radars. We use the term ‘decision adaptive’ in contrast to ‘data adaptive’ whereby the output of a tracking algorithm initializes the weight vector of the antenna array such that the main formed beam can be steered toward a desired, conjectured...
