Ground radar is a broad term that can refer to any type of radar system that is positioned on the ground. It is used for a variety of purposes, including weather monitoring, military surveillance, and space surveillance. The range of a ground radar system depends on the type of radar and the power of the transmitter.
Military ground radar is a type of radar system used to detect and track aircrafts, ships, and other objects that potentially pose a threat to national security. It can also be used for guiding missiles and other weapons systems. These powerful systems are key to gathering valuable information, especially for protecting people and infrastructure from attacks.
Common types of military ground radar include:
Weather radar, also called weather ground radar, detects precipitation in the atmosphere such as rain, snow, and hail. Meteorologists use this essential tool for forecasting weather conditions and monitoring severe events. These systems can be found at airports, weather stations, or other strategic locations.
Weather radar typically:
The two main types of weather ground radar are pulsed radar and continuous-wave radar. Pulsed radar uses short bursts of radio waves and their echoes to measure distance to precipitation. Continuous-wave radar uses a constant stream of radio waves and the strength of their reflection to measure distance to precipitation. Pulsed radar is typically used for longer distances and continuous-wave is typically used for shorter distances.
Space surveillance radar systems detect and track objects in space such as satellites, spacecrafts, and missiles. These radar systems are powerful enough to detect objects at long ranges but are expensive and complex to operate. Space surveillance radar systems are typically used for:
No matter the application of a ground radar system, RF cables provide a reliable and efficient way to transmit and receive RF signals from the antenna to the radar’s electronic components. The connection of these coaxial cables ensures the RF signals can be transmitted and received with minimal loss, as they require high accuracy and consistency. Depending on the specifics of the ground radar application, the type of coaxial cable used can vary.
Advantages of RF cables for ground radar include:
Coaxial cable failure can lead to several issues, including loss of radar capability, signal attenuation, and interference. To prevent coaxial cable failures, ground radar systems are typically designed with multiple coaxial cables as the connection between the transmitter and receiver. These systems also undergo rigorous testing, particularly environmental testing, to ensure the coaxial cables will withstand the environment. To reduce risk of cable failure, inspect cables regularly, install high-quality cables, make sure installations are done properly, and replace cables at the first sign of damage or inconsistency.
Our standard LMR® is the industry standard in high-performance broadband, flexible, low-loss 50 Ohm coaxial cables idea for lower frequency radars where phase is not critical, but loss might be. A rodent and pest resistant option with a non-hazardous and non-toxic jacket is also available.
PhaseTrack® cable assemblies are designed for applications demanding minimal phase change over temperature. All PhaseTrack cables use a proprietary TF4® dielectric that does not have the abrupt shift in the phase that occurs with solid- or tape-wrapped PTFE-based products under normal room ambient temperature conditions.
TCOM® is a UV-resistant polyethylene jacketed cable commonly used for C band, S band, and x band radars operating where phase is not critical.
MaxGain® is an ultra-low loss, flexible microwave coaxial cable for high frequency radars up through mm wave bands where low loss is critical
