Reducing the reflection of radar radio waves when they are passed through one or more stratified mediums.
The systems and methods described here are about making radar radio waves travel better through different materials, like those found in the atmosphere or other substances. The radar system they propose helps reduce the bouncing back of radio waves when they pass through these materials.
To do this, a "matching layer" is designed using a special model. This matching layer is like a buffer between the radar system and the material the waves are passing through. By choosing the right material for this matching layer and putting it between the radar system and the material, the reflection of radio waves is reduced. This makes the radar system work better and reduces the amount of energy lost in the process.
- Reduction of Reflections: The radar system reduces reflections of radio waves when they pass through one or more stratified mediums by using a specially designed matching layer.
- Matching Layer Design: The matching layer is designed using a Chebyshev multi-section transformer model, which computes the dielectric constant and loss tangent based on the stratified medium.
- Material Selection: The dielectric material for the matching layer is selected to match the computed dielectric constant and loss tangent.
- Placement of Matching Layer: The matching layer is placed in contact with the stratified medium to reduce reflections and bi-directional losses.
- Optimization for Azimuth Range: The matching layer covers the entire azimuth range and is designed to have a thickness equal to a quarter of the guided wavelength of the radio waves.
- Reduced Reflections: By using a matching layer with properties tailored to the stratified medium, the radar system minimizes reflections, enhancing signal clarity and accuracy.
- Broad Field of View: The system achieves reduced bidirectional losses over a large field of view, improving radar performance in diverse operational conditions.
- Efficient Material Matching: The Chebyshev multi-section transformer model ensures precise matching of dielectric properties, leading to optimal performance.
- Versatile Application: The technology is applicable to various stratified mediums, including multi-layered objects, painted surfaces, and radomes.
- The prototype magnetron apparatus includes a cylindrical body, a plurality of vanes, and multiple straps and coverings arranged circumferentially around the vanes.
- The straps and coverings are strategically shorted and spaced to maximize capacitance and minimize electron interference.
- Copper is used for the coverings to ensure high conductivity and durability.
