“…To achieve that high resolution, antenna aperture should be increased. Considering the cost and high reliability, system employs separated transmitting and receiving antennas, transmitting wide beam and receiving narrow beam, monopulse angle measurement and high range resolution techniques [4] .…”

Collision avoidance radar for trains is significant for safe transportation. In order to realize a low cost collision avoidance radar and high performance of azimuth accuracy, we have developed MMW (millimetre wave) radar, which employs switched phased array and frequency stepped technology. This paper analyses the radiation patterns of transmitting/receiving antennas and compensation method for amplitude/phase errors of synthetic wideband frequency stepped radar. To confirm the operation of the radar, low cost millimetre-wave collision avoidance radar was fabricated.Lots of experiments confirmed a high azimuth and range resolution.

“…Objects such as luggage and even humans may be present on the tracks. The radar-based application senses the presence of one or more objects on the tracks and can identify the type of object from a set of known objects [10].…”

“…The total least-squares matrix pencil method is employed to extract the complex natural resonances (CNR) of the object. The CNR of the object under consideration, and the CNR of objects which may be found on railway platforms, are presented to the discrimination process proposed in [10] to classify the object. The method is shown to reliably classify humans and other objects on or near railway platforms and is capable of distinguishing one object from another, such as an item of luggage from a person.…”

Phased arrays are diversely applied with some specific areas including biomedical imaging and therapy, non-destructive testing, radar and sonar. In this thesis, the matrix pencil method is employed to reduce the number of elements in a linear ultrasound phased array. The noniterative, linear method begins with a specified pressure beam pattern, reduces the dimensionality of the problem, then calculates the element locations and apodization of a reduced array. Computer simulations demonstrate a close comparison between the initial array beam pattern and the reduced array beam pattern for four different linear arrays. The number of elements in a broadside-steered linear array is shown to decrease by approximately 50% with the reduced array beam pattern closely approximating the initial array beam pattern in the far-field. While the method returns a slightly tapered spacing between elements, for the arrays considered, replacing the tapered spacing with a suitably-selected uniform spacing provides very little change in the main beam and low-angle side lobes. iii ACKNOWLEDGMENT I would like to thank Dr. Robert McGough for his support and guidance during my master's degree, and for the opportunity to be part of the Biomedical Ultrasonics and Electromagnetics Lab. His experience and insight into biomedical ultrasound, phased arrays, research, and publication was an invaluable resource during my research and while writing my thesis.

“…Non-imaging UWB target detections have been conducted where promising techniques fall into two categories: resonant [10] and polarimetric [11] based approaches. The natural resonant frequency from late time response caused by the creeping wave was evaluated for detection in previous research such as military aircraft models [12] and shapes [13]. Owing to the overlap of resonant frequencies, the resonant approach lacks the ability to know the quantity of eggs [14].…”

Abstract-Detection of packages or storage containers relies heavily on the use of radio frequency identification (RFID) tagging, though such technology provides no means to determine the quantity of items within them. This paper presents a comprehensive study of ultra wideband (UWB) detection in the reactive near field as a low cost, low power way of detecting solid items within a package to complement RFID. For proof of concept, egg boxes within a smart fridge are used as a chosen test case. Simulations and measurements are carried out to evaluate the filtering of the UWB impulse response from which it can resolve the quantity of eggs in a box, using an array of sensors either attached to the package or placed underneath. Correlation coefficients are derived as a metric of this filtering in a reactive near field detection scenario. The robustness of the approach is further evaluated by considering other food cluttered around and above the egg box. The results show smart packages which detect an item directly above the sensor are not affected by surrounding clutter.Index Terms -Reactive near field, ultra wideband (UWB), smart fridge, Internet of things (IoT), pulse filtering
