GBPPR Homebrew Radar Experiments


Overview

One of the biggest experiments I've always wanted to work on is a homebrew radar system.  No, not some little ultrasonic range finder using pre-made kits, but a true high-power pulse (and maybe Doppler) radar system.  And I think it's now possible...

This project will be continuously "in development."  I have no idea if the final outcome will even work, but I'll try to make all the experiments public and fairly-well documented.  The overall work will be done in a series of sub-sections over the next few months (or even years).  If it all works - great.  If it doesn't...  It'll look cool, and you'll have nice beacon to attract anti-radiation missles.

A very detailed description of how radars operate, and the design of their major component sections, is available in the U.S. Army Aviation Course - Subcourse MM5005: Radar Transmitter manual.  This manual is also available online.

MIT has a free online course Build a Small Radar System Capable of Sensing Range, Doppler, and Synthetic Aperture Radar Imaging which describes how to build a simple S-band radar system.

  20. "The function of a Low Probability of Intercept (LPI) radar is to prevent its interception by an Electronic Support (ES) receiver.  This objective is generally achieved through the use of a radar waveform that is mismatched to those waveforms for which an ES receiver is tuned.  This allows the radar to achieve a processing gain, with respect to the ES receiver, that is equal to the time-bandwidth product of the radar waveform.  This processing gain allows the LPI radar to overcome the range-squared advantage of the ES receiver in conventional situations.  Consequently, a conventional ES receiver can only detect an LPI radar at very short ranges <3 nm).  The focus of this thesis was to develop an ES receiver to detect LPI radar signals with the same sensitivity as conventional pulse signals.  It implements a detector which employs a technique, known as 'deramping,' that forms an adaptive matched filter to the linear FMCW LPI radar signal in order to achieve the processing gain that is equal to the received signal's time-bandwidth product."
