Development of a synchronisation and video conversion unit for Denel Overberg Test Range's tracking radar
… the re-development of a subsystem of the tracking radar (TR) at Denel Overberg Test Range (OTR), defined as the Synchronisation and Video Conversion Unit (SVCU). The SVCU performs the task of baseband video processing, generation of all synchronisation triggers, and timing within the TR. …

Cognitive Radar Applied To Target Tracking Using Markov Decision Processes
… States. Future platforms and devices, such as radars and radios, need to be adaptive to their spectral environment in order to continue serving the needs of their users. This thesis considers an environment with one tracking radar, a single target, and a communications system. The …

Value of Machine Learning and Cognition on Target Tracking
… This thesis considers an environment with one tracking radar, a single target, and a communications system that can passively interfere with the radar system. Three separate agents, Sense and Avoid, Machine Learning, and "Optimal", are tasked with the channel selection problem for radar …

Developing a Methodology to Detect Partial Failures for Dynamic Systems
… in dynamic systems such as Fire Control System Tracking Radar (TR) onboard Naval Ships. Partial failures do not necessarily shut down the system immediately but cause degradation of operational performance. Previous work has shown that experts in the field of failure detection, test point …

Study of the TR Synchronization and Video Conversion Unit
… Video Conversion Unit (SVCU), a subsystem of the tracking radar (TR) at Denel Overberg Test Range (OTR). The SVCU synchronizes all the radar sub-systems and also converts the returned RF target signals to digital numbers. The technology within the SVCU is outdated and spares are scarce if not …

Creation of a Cognitive Radar with Machine Learning: Simulation and Implementation
In this paper we address radar-communication coexistence by modelling the radar environment as a Markov Decision Process (MDP), and then apply Deep-Q Learning to optimize radar performance. The radar environment includes a single point target and a communications system that will potentially …

Exploitation of Modes in Circular Antenna Arrays
… the first time with application to simultaneous tracking and communication with the target based on BER of the composite signal transmission. <br/><br/>3) Thirdly, the linearity of the modes was exploited, which allows for superposition of radiated beams using MMCA. The multiple beam formation …
