Synthetic Aperture Radar Systems

Synthetic Aperture Radar (SAR) is a technique which uses signal processing to improve the resolution beyond the limitation of physical antenna aperture. In SAR, physical movement of the actual antenna is used to synthesize electrically large antenna aperture. Application note describes efficient…

In this application note, simulation of the Radar Cross Section (RCS) in time-domain is described in WIPL-D Software suite. The products used are WIPL-D Pro and WIPL-D Time Domain Solver. Well known metallic object NASA almond was illuminated by plane wave using Gaussian…

This paper presents modeling and simulation results of monostatic Radar Cross Section (RCS) for scaled model of generic airplane in WIPL-D software. We present simulation times, memory requirements and hardware used for two types of solvers: CPU and GPU. The airplane is modeled…

One of typical applications of EM tools in automotive radar industry would be accurate prediction of radiation pattern of automotive radar antenna mounted on the front part of a car. Also, near field distribution in front of the car shell (usually in presence…

Determining a resonant frequency of a cavity is a frequent task in analyzing various microwave systems. Due to the shape and interior structure of the cavity, it is often not possible to perform resonant frequency calculations by applying analytical formulas. In such cases, direct…

Simulation of reflector antennas can be very challenging for MoM codes. Despite that, WIPL-D Software, as MoM code based on SIE, appears to be very suitable and efficient tool used for simulating large reflector antennas. Reflector, as part of the…
