Bangalore-based Alpha Design Technologies has secured a contract to supply its new mobile very-high-frequency (VHF) radar to ...

Antennas used with ground penetrating radar (GPR) come in different shapes and sizes. The largest antennas typically radiate the lower frequencies necessary to detect the deepest targets.

this system is a passive radar system that uses radio waves already present in the environment to track objects. A reference antenna is used to listen to the target frequency, and in this ...

compared to a reference power density at a distance of 1 meter from the radar antenna. Base reflectivity images are available at several different elevation angles (tilts) of the antenna ...

The Japan Ministry of Defense (MoD) has received the first AN/SPY-7(V)1 radar antenna from Lockheed Martin for integration with the Aegis System Equipped Vessel (ASEV). The delivery, facilitated ...

Oso Semiconductor, a developer of power-efficient, high-performance, low-cost chipsets for next generation wireless communication and sensing applications, today announced it has raised an ...

India's Defence Research and Development Organisation (DRDO) has unveiled a new very-high-frequency (VHF)-band surveillance ...

However, smaller wavelengths have the advantage of being able to be projected in sharper beams by smaller antennas and generally have higher precision (Bruderer 1997). Radar has several benefits ...

Heliospace built two different types of radar antennas for the Europa Clipper mission: two High Frequency (HF) antennas, which deploy to over 55 ft in length, and four smaller Very High Frequency ...
