Radar clutter is a significant challenge in radar systems, particularly when attempting to detect legitimate targets in environments filled with unwanted reflections. Clutter comes from objects like buildings, trees, mountains, or even the sea surface, all of which can produce strong radar returns that obscure the objects radar operators actually want to track, such as aircraft or ships. The ability to suppress this clutter is critical for effective radar operation, especially in civil aviation and maritime surveillance.

Radar systems rely on transmitting pulses of electromagnetic energy and receiving the reflections from targets to determine their location and movement. Two critical parameters in this process are Pulse Repetition Frequency (PRF) and range resolution.

This article describes how FreeScopes Basic III and IV enhance ATSEP training across Communication, Navigation, and Surveillance for Levels 2–5 in ICAO taxonomy.

In today's video, we demonstrate how to create plots and tracks using FreeScopes.

Radar systems can be broadly categorized into two types: coherent and non-coherent. The key difference between these two systems lies in how they process the returning radar signals.

Tracking moving objects is one of the core functions of radar systems, particularly in applications like air traffic control (ATC) where detecting and following aircraft is vital for safety.

FreeScopes AI 1 equips ATSEP trainees with skills in target detection, data interpretation, and anomaly analysis for effective AI-based air traffic management.

The Radar Cross Section (RCS) is a crucial factor in radar systems, as it determines how detectable an object is. In simple terms, RCS is a measure of how much radar energy a target reflects back to the radar receiver. This reflection varies based on the size, shape, material, and orientation of the object. Objects with larger RCS values, such as aircraft or ships, tend to reflect more radar signals and are therefore easier to detect. Conversely, smaller objects or those designed to absorb radar waves (like stealth aircraft) have lower RCS and can evade detection more easily.

Radar antennas are a critical component of any radar system, determining how radar signals are transmitted and received. In radar technology, two key properties of antennas are beamwidth and polarization, both of which directly affect the radar’s ability to detect and track targets. SkySim provides a hands-on platform for exploring these properties, allowing users to adjust antenna configurations and observe how they influence radar performance.
