    GBSAR-Proc
    (Cranfield University, 2019-08-22 15:56) Elgy, James
    The GBSAR-Proc Python package is designed to load and process data gathered from Cranfield University's ground based Synthetic Aperture Radar (SAR) system. Included in the package are a series of classes designed to manipulate raw data, process it into range profiles and finally use the Backprojection Algorithm to plot high quality near-field SAR images. In addition to the more common planar SAR images, there is functionality to both generate and plot volumetric SAR images, formed on either the CPU or GPU.

    Tuning of a Complementary Orientation Filter Using Velocity Data and a Genetic Algorithm
    (Cranfield University, 2024-01-08 14:59) Maton, Dariusz; Economou, John; Khan, Irfan; Galvao Wall, David; Cooper, Rob
    The data uploaded here contains the experimental and simulation data used to demonstrate the utility of the optimisation of a complementary orientation filter using a genetic algorithm (GA). Implementation of the GA in MATLAB is provided as well as supporting functions such as the zero velocity update and weighted-relative velocity error metric (W-RVE). The novelty of the work is the optimal tuning of the complementary filter gain using a GA and velocity data of an object moving in the locally level frame. Optimal filter gains are encoded a Takagi-Sugeno (TS) fuzzy inference system with four Gaussian membership functions. This offers a transparent and traceable encoding.
