The dual-band radar (DBR) aboard the Navy aircraft carrier USS Gerald R. Ford (CVN-78), the ship’s primary sensor system, struggled to perform during a pre-deployment exercise and suffered failures as ...

[Andy] sent in this pdf (mirror) describing a simply diy UWB Radar project. It’s not intuitive, but by using a wide frequency range for low power, short distance purposes, the system should ...

Most detectors use radar frequencies to figure out how far ahead ... However, there is always a possibility that the same bands used by law enforcement and their radar guns are used by others.

Meanwhile if you’re interested in Doppler radar, here’s how to design one for a lower frequency.

What is a high-frequency radar? High-frequency or HF radar is a shore-based remote sensing system used to measure offshore water surface currents by sending a low-power electromagnetic pulse over the ...
