Space-based radar systems are designed for global on-demand surveillance and resource monitoring. These radar systems operate in outer space and allow for the integration of data from manned and unmanned spacecraft. It provides access to any location on Earth, provided it has the proper orbit, which is especially useful for more extreme or unsafe environments that are difficult to observe from an aircraft. The global coverage, high resolution of images, and perpetual surveillance of an area are key advantages of space-based radar.
In the military, space-based radar systems are typically a constellation of radar satellites for tracking aircrafts, ocean vessels, and land vehicles or for intelligence gathering on foreign countries.
In commercial spaces, space-based radar systems are used for high resolution imaging, ocean topography research, environmental monitoring, and monitoring of wind speed and direction.
In space-based radar systems, RF signals detect and track various objects. To accomplish this, they must be transmitted and received with a high degree of accuracy. RF cable assemblies provide the connection between the radar transmitter and receiver. The specific RF cable assembly used for a space-based radar system depends on the operating frequency and radiation requirements of the environment.
Using coaxial cables in space-based radar systems offers many advantages:
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.
The SiO2 semi-rigid cable assemblies are used in applications demanding the ultimate in phase tracking performance and extreme environments.
