Synthetic Aperture Radar and Inverse Synthetic Aperture Radar (SAR/ISAR) systems are powerful instruments for monitoring and imaging of stationary and moving objects during throughout the day and all weather conditions. Range resolution is achieved by using high informative wideband frequency emitted signals subjected to compression. Cross-range or azimuth resolution is achieved by aperture synthesis.

The tutorial will address both theoretical and specific technical concepts encountered in the analysis, measurement and design of linear noisy circuits. Although the material to be presented can be found in many published books and papers, it is usually broadly scattered and not necessarily presented in orderly sequence. It will cover tutorial exposition of some key physical and network theoretic ideas as applied to practical models, circuits and measurement methods. It is therefore addressed to those interested in developing a good understanding of noise in microwave devices and circuits. The subjects to be covered are:

What is the 5th generation (5G) wireless communication? Nobody could tell us an exact definition at present. However, some emerging and potential technologies have attracted more and more attention. Of which, massive MIMO, millimetre wave, Beamforming, Full Duplex technologies are considered to be the key technologies for 5G wireless communications. Traditionally, the antenna in mobile communication systems is a passive element and generally is separated from the RF transceivers. To design the future antennas for mobile terminals, not only the bandwidth and antenna efficiency need to be acceptable, but also beam pointing and beam coverage is essential knowledge of the mobile channel. It is expected that the antennas or the antenna system will be adaptive. Moreover, the antennas or the system should not only cover the new frequency bands but also can be tightly integrated with the existing systems (4G) and evolutions of the 4G system primarily at the conventional sub-6 GHz bands. Several structures are available for designing multiband antenna such as planar inverted-F antenna (PIFA), monopole antenna and slot antenna etc. For example, by using monopole element, multiple resonances can be excited to cover large bands with reasonable system size. Moreover, at either lower microwave band or millimetre wave band, the antenna will be seamlessly integrated with RF transceivers and even with RoF or ADC (DAC) and E/O (O/E). Nowadays, for instance, mobile phones are required to be thin, elegant and have metal body along with other electrical requirements such as supporting multiple radios, large battery, high resolution display and camera etc. Several multiband antennas are required with sufficient isolation between them to support multiple radios and are essential for multifunctional devices. Therefore, the antenna for 5G communication systems will have distinct characteristics compared to traditional antennas. The tutorial will focus on the recent research advances in 5G antennas in interaction with the 5G Key technologies ingredients. It will be a good opportunity for students, professors and researchers in the field to brainstorm on and to identify the antenna's requirements to satisfy the 5G key emerging technologies.

Nowadays, microwave imaging is broadly used for non-destructive testing, concealed weapon detection, through-the-wall imaging, land mine detection, road pavement inspection, underground facilities survey, archaeological investigation, imaging of biological tissues, etc. This list is still expanding, especially at sub-mm wave frequencies. In all cases, the scene of interest is illuminated by natural or man-made sources and image is formed based on received scattered electromagnetic field. The two principal modalities of image formation are analogue (when image is formed by means of lens or mirrors following quasi-optical approach) and digital (when image is formed by means of digital signal processing of scattered field, which is measured at different spatial locations by antennas). While in the former case intensity of electromagnetic field in a single point of the image corresponds to scattering/reflection properties of a corresponding area of the scene, in the latter case electromagnetic field amplitude and phase measured by an antenna at a particular position depend on scattering/reflection properties of the whole scene. In both cases the image cross-range resolution is mainly determined by the electrical size of the imaging aperture (area, at which the scattered field is collected by mirror, lens or antennas) and the range of the scene. The tutorial is focused on selection of measurement locations of the scattered field within the imaging aperture and main digital processing algorithms used to create an image from the measured amplitude and phase of the scattered field.
