dc.description.abstractRadar systems have become highly dynamic with the advancements in all-digital radar architectures. All-digital radar architectures introduce the potential for dynamic beamforming. This thesis will detail the fundamentals that are the foundation of radar signal processing (RSP) and modeling a digital phased array radar. This thesis will detail the techniques used for digital beamspoiling. The intentional beamspoiling is intended to improve the trackers’ ability to track a target continuously. When a high-speed target falls out of a beam due to a maneuver, the radar will spoil the transmit beam illuminating a wider scene. The wider illuminated scene allows for a higher likelihood of accurately detecting the target, allowing the tracker to track the target continuously. This thesis will discuss the theory and application of the trackers used in the simulation. With the beamspoiling and trackers, this thesis will analyze the ability of an all-digital phased array to track a target utilizing dynamic beamforming to improve the tracking performance. Finally, it will detail the improvement of the trackers’ ability to track when utilizing beamspoiling for specific situations, allowing the radar to track targets for a more extended time. The results varied based on the amount a transmit beam was spoiled due to the loss in SNR that naturally occurs from the decrease in power density.en_US
