Kalman Filter Tracking Radar System with an Adaptive Search Space Resolution Technique
Abstract
This thesis develops a radar system to improve tracking by avoiding loss of target track when signal-to-noise ratio is low or when the target leaves the main beam of the antenna. Target tracking is performed by a Kalman tracker with two modes. The default mode uses a significant number of phased array elements, thereby forming a narrow beam for target search, which is referred to as high resolution (HR) mode. If the target leaves the main beam, the radar system enlarges the beam and thus can re-capture the target. This is accomplished by lowering the number of antenna elements, which is referred to as the low-resolution (LR) or wide search mode. To maintain SNR, the radar is assumed to increase the transmit output power. Once the target is recaptured, the radar switches back to high-resolution mode. Thus, this radar is an integrated beamsteering and tracking system.
