Cross-validation of spaceborne radar and ground polarimetric radar observations
There is great potential for spaceborne weather radar to make significant observations of the precipitating medium on global scales. Unlike other instruments, such as light detecting and ranging (lidar) systems that operate in the optical region, and thermatic mapping systems that use short …

Adaptive Radar with Application to Joint Communication and Synthetic Aperture Radar (CoSAR)
Until recently, the functionality of radar systems has been built into the radar's analog hardware, resulting in radars which are inflexible and that can only be used for a specific application. Modern systems, however, driven by the ever increasing speed of processors and data converters - …

Radar tracking system development
… sensor on the ASTB. It is a passive X-band radar receiver located on the nose of the plane. The IH serves as a truth sensor for other RF systems on the test bed and is controlled by an onboard tracking system, the Seeker Computer. The Seeker Computer processes IH data in real-time to track …

A study of bistatic radar and the development of an independent bistatic radar receiver
… report contains a literature review of bistatic radar and also describes an experimental L-Band bistatic radar receiver which was built at the University of Cape Town. In a bistatic radar the transmitter and receiver are separated by an amount which is comparable to the distance to the targets …

Pulse Coding for ionospheric radar
… Advanced Digital Ionosonde) is an active radar, which is used to probe the structure and motion of the ionosphere, such as virtual height, drift velocity, angle of arrival, echo intensity, etc. It is mainly composed of a control platform (like a personal computer PC), the plug-in DDS …

Doppler-only synthetic aperture radar
SAR has traditionally been performed using high-range resolution data. This thesis is a proof-of-concept that the imaging process can be performed using high-doppler resolution data. The system requires a simple continuous wave transmitter, and the signal returns are confined to a narrow band. …

Target Tracking Via Marine Radar
… due to collision and habitat loss. Since then, radars have been deployed to study the behavior of birds towards wind turbines. Radars employ target tracking for identifying the targets (birds) accurately and efficiently. Several methods of tracking were developed to improve the tracking …

Some contributions on MIMO radar
… the potential of MIMO approaches in the radar context. In communications, MIMO systems combat the fading effects of the multi-path channel with spatial diversity. Further, the scattering environment can be used by such systems to achieve spatial multiplexing. In radar, a complex target …

Multiple frequency atmospheric radar techniques
… very high frequency (VHF) atmospheric radars, especially with regards to the two-frequency technique known as frequency domain interferometry (FDI). This technique consists of transmitting alternate pulses on two distinct carrier frequencies. The two resulting time series are used to …

Remote cardiac monitoring using radar
… this problem, an ultra wide band (UWB) pulse radar and a fixed-frequency amplitude based radar were constructed and evaluated. The UWB radar was not reliable and did not produce repeatable results, but the fixed-frequency radar successfully recorded heartbeat signatures from twelve human …
