A lot of progress has been made for automotive radar during the last years. There are two types of automotive radar; “long-range radar at 77GHz with a range capability up to 200m“ for automatic cruise control (ACC) and “short-range radar at 24/26 and 79GHz up to 30m“ for anti-collision. Long radar with narrow radiation beam enables a automobile to maintain a cruising distance, while short-range...

The design of a weather radar system, as well as its scanning strategies, involves various tradeoffs based upon the goal of observing certain features of interest. The tradeoffs made in this design are based on certain assumptions about the performance of the radar system and on characteristics of the feature of interest. Often, the development of algorithms and optimal scanning strategies requ...

In recent years, several emerging technologies in modern radar system design are attracting the attention of radar researchers and practitioners alike, noteworthy among which are multiple-input multiple-output (MIMO), ultra wideband (UWB) and joint communication-radar technologies. This thesis, in particular focuses upon a cognitive approach to design these modern radars. In the existing litera...

In this paper, we quantify the temporal opportunities for secondary access to radar spectrum. Secondary users are assumed to be WLANs which opportunistically share the radar frequency band under the constraint that the aggregate interference does not harm radar operation. Each WLAN device employs dynamic frequency selection (DFS) as a mechanis m to protect the radar from the interference. We al...

This thesis presents selected research papers and patents written by Simon Watts between 1985 and 2012 on the topic of the modelling of radar sea clutter. This work has been based on the development and exploitation of the compound K distribution model for the amplitude statistics of radar sea clutter. It has covered the development of the model, through the analysis of recorded radar data, to ...

considering a) that radar systems can produce interference to digital radio-relay systems (DRRS), which gives rise to regular bursts of errors related to the operational characteristics of the radar e.g. the radar antenna rotation rate; b) that the importance of radar systems is recognized worldwide, but that nevertheless efforts should be made to reduce the levels of spurious emissions from su...

Multifunction phased array radars have the ability to steer the radar beam electronically, adapting its parameters according to how the radar perceives the environment. Thus, the effective allocation of the available resources is very important. A model of a multifunction phased array radar was implemented to examine the complexities involving this type of radar. Additionally, approaches to ada...

Biand multistatic radar are expected to benefit from their separation of transmitter and receiver that denies receiver recognition by ARM, favours covered operation by their silent receivers, has higher detection possibilities of stealthy objects and is less vulnerable to jamming. The requirements of synchronisation in a separated transmitter-receiver system are discussed. The processing in bis...

High-precision radiometric calibration and synchronization compensation must be provided for distributed radar system due to separate transmitters and receivers. This paper proposes a transponder-aided joint radiometric calibration, motion compensation and synchronization for distributed radar remote sensing. As the transponder signal can be separated from the normal radar returns, it is used t...

In this paper, an analysis of a target location estimation system using the best linear unbiased estimator (BLUE) for high performance radar systems is presented. In synthetic environments, we are here concerned with three key elements of radar system modeling, which makes radar systems operates accurately in strategic situation in virtual ground. Radar Cross Section (RCS) modeling is used to d...
