Pointer to data wanted please -- looking for a primer on phased array radar

Click For Summary
A user is seeking a primer on phased array radar (PAR) focusing on the physical requirements for operating in the 800MHz/5GHz bands and the circuits used for phase adjustment of transmitter antennas. They express interest in both transmitting and receiving capabilities, ideally from small surfaces, while acknowledging potential mechanical limitations. The discussion highlights the recent rise of affordable DIY radar sensor boards, suggesting that existing literature may cover these topics. Concerns about operating within legal frequency bands are also mentioned, emphasizing a desire to avoid illegal transmissions. The conversation points to the need for authoritative resources or academic institutions specializing in RF technology in Southern California.

Fair warning: I can handle basic physics stuff, but probably nothing post-collegiate. :)

Specifically, I'm looking for a primer on phased array radar that will tell me two things: 1) what are the practical physical (antenna) requirements for running a PAR system in the 800MHz/5GHz bands, and 2) What kind of circuit is used to do the phase-adjustment work for the various transmitter antennae?

I know this sounds outlandish, but with the recent explosion of cheap DIY/Arduino radar sensor boards, it seems like this RF territory must have been pretty thoroughly thrashed out - somewhere there is a textbook or batch of papers that will talk about this with some authority, right?

Alternatively, are there any colleges in southern California with RF labs/departments that specialize in this kind of stuff?

Are you looking to do both TX and RX with the PAR, or just RX with angular sensing of the source direction?
 
ideally I would do both tx and rx from either one or two relatively small surfaces (2cm radius-ish) but if that's mechanically prohibited due to wavelength, other solutions (like a separate transmitting antenna) can be used. This would be test/prototype gear, lovingly produced. :)

Would this be in the ISM band? You need to be careful where you to transmitting radar signals... :smile:
 
I really don't know what band would be used... there was some speculation in the reviews of the arduino radar sensors that they operated in the shorter wavelengths, so that's what I was basing my questions on. I have NO intention of producing, using, or proselytizing illegal radio transmissions! My life is complicated enough without legal issues. :)

Thread 'Electric power distribution from powerplant to homes'

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
