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 …

Innovative Combinatorial Strategies for the Synthesis of Radar Tracking Antenna Systems
In the framework of the synthesis of monopulse array antennas for search-and-track applications, the thesis focuses on the development and the analysis of a method based on the sub-arraying technique aimed at generating an optimal sum and compromise difference patterns through an excitation …

A Particle Filtering Approach to Joint Passive Radar Tracking and Target Classification
… are the first to provide a joint framework for tracking and classification that realizes the full potential of such an approach. Our joint formulation consists of three key developments: (1) an aerodynamically valid flight model that relies upon aircraft-specific coefficients such as the wing …

The Extended Preferred Ordering Theorem for Radar Tracking Using the Extended Kalman Filter
… problem in nonlinear estimation exists in radar tracking. Usually radar detections provide instantaneous position measurements in radar (polar) coordinates at discrete times, while tracks (estimated positions and motions over continuous time) are determined in rectangular coordinates; and …

Accelerating Gauss-Newton filters on FPGA's
Radar tracking filters are generally computationally expensive, involving the manipulation of large matrices and deeply nested loops. In addition, they must generally work in real-time to be of any use. The now-common Kalman Filter was developed in the 1960's specifically for the purposes of …

Evaluation of avian hazards to aircraft at Dallas/Fort Worth International Airport
… all air traffic below 3,000 feet. Air traffic radar tracking data suggests that arriving jets may enter the high-risk airspace below 3,000 feet AGL as far out as 15 statute miles from the center of the airport (propeller planes enter this airspace as far out as 25 statute miles) (Figures 10 and …

Performance analysis and algorithm enhancement of feature-aided-tracker (FAT) simulation software using 1-D high-range-resolution (HRR) radar signature profiles
… and appended to provide a robust ground-target radar tracking simulation tool. It utilizes algorithms from the LL UAV Radar Moving Target Tracker (1991) and the LL FAT Tracking Software (2002). One-dimensional High-Range-Resolution (HRR) radar signature target profiles were used to assist in …

Radar and LiDAR Fusion for Scaled Vehicle Sensing
… driving systems, but often lack automotive-grade radars in their sensor suites. To overcome resolution issues when using a radar at small scale, a high-level sensor fusion approach between the radar and automotive-grade LiDAR was proposed. The sensor fusion approach was expected to leverage the …

Dynamic model for space-time weather radar observation and nowcasting
… framework of the dynamic model for space-time radar observations has been developed in the current research. There exist three difficulties in modeling spacetime radar observations: 1) high dimensionality due to the high-resolution radar measurements over a large area, 2) non-stationarity due …

Bug vision : experiments in low resolution vision
Tracking multiple people using cameras is similar to the well-studied problem of tracking multiple radar or sonar echoes. This thesis shows that current camera-based tracking algorithms convert each image in a video sequence to a list of targets through a segmentation step, and pass this target set …

Scheduling of costly measurements for state estimation using reinforcement learning
… to a high-dimensional nonlinear problem in radar tracking and is able to outperform the best available heuristic by as much as 35%. In treating these problems, it is shown that a useful synergy exists between learned and heuristic policies, with each helping to verify and improve the …

Adaptive OFDM Radar for Target Detection and Tracking
… frequency division multiplexing: OFDM) radar signal. The frequency diversity of the OFDM signal improves the sensing performance since the scattering centers of a target resonate variably at different frequencies. In addition, being a wideband signal, OFDM improves the range resolution …
