This paper describes the development and testing of low cost Inverse Synthetic Aperture Radar (ISAR) turn table system with a machine learning back-end. The ISAR sensor is based on audio components which mimic the functioning of a radar system but at

This paper furthers the investigation into modulation effects of propeller-powered aircraft on signals sensed by multistatic FM-band passive radar sensors. Previous results have demonstrated that a passive radar system consisting of a single bistatic

Many studies have suggested that a fully polarimetric radar or a bistatic radar can improve the classification and recognition of airborne targets due to enhanced target information. This paper makes use of the information theoretic concept of mutual

Either passive calibration targets are expensive and complex to manufacture or their bistatic radar cross section (RCS) levels are significantly lower than the monostatic RCS levels of targets such as spheres, dihedral, and trihedral corner reflector

The radar cross section (RCS) of passive calibration targets is relatively low, which leads to a commensurate increase in the uncertainty of the radar's calibration. To address this deficiency, an active radar calibration (ARC) target was developed,

In this paper, a three-layer homogeneous medium (air, vegetation, and ground) is developed with the electrical properties (relative permittivity and conductivity) estimated using experimental measurements. This is the first step toward the developmen
