What are the characteristics of a radar wave?
A radar wave refers to the electromagnetic waves used in radar systems to transmit and receive signals. These waves are generally in the radio frequency (RF) or microwave portion of the electromagnetic spectrum. Key characteristics of radar waves include:
Frequency: Radar waves have specific frequencies that determine their wavelength and energy. Radar systems operate at frequencies ranging from several megahertz (MHz) to tens of gigahertz (GHz), depending on application requirements such as range, resolution and atmospheric conditions.

Wavelength: The wavelength of radar waves corresponds inversely to their frequency. Higher frequencies have shorter wavelengths, allowing radar systems to achieve finer resolution and better target discrimination. Lower frequencies, with longer wavelengths, are more suitable for long-range detection and penetration in atmospheric conditions.
Propagation: Radar waves propagate in straight lines unless affected by reflection, diffraction or refraction. They travel at the speed of light in the medium they pass through, typically close to the speed of light in a vacuum (~3 × 10^8 meters per second).

Polarization: Radar waves can be polarized, meaning that the orientation of their electric field vector oscillates in a particular direction as they propagate. Polarization can affect the way radar waves interact with objects and surfaces, influencing the radar’s ability to detect and characterize targets.
Power and pulse duration: Radar waves are emitted in pulses rather than continuously. The power level of these pulses, along with their duration and repetition rate, determines the radar’s maximum range, sensitivity to targets, and ability to distinguish between different objects.
Understanding these characteristics of radar waves is essential for designing radar systems suitable for specific applications, optimizing performance parameters and interpreting responses (echoes) received from targets or objects in the field of view. radar vision.
