The Radar Equation | Understanding Radar Principles

Learn how the radar equation combines several of the main parameters of a radar system in a way that gives you a general understanding of how the system will perform.
The radar equation is a function of transmit power, antenna gain, transmit frequency, radar cross-section of the object, and the propagation through the environment and radar components. Walk through each of these steps and watch a demonstration of how they contribute to the total received power of the reflected signal back at the radar.

This is by far the best explanation of radar - great detail and simple enough for anybody to grasp. Thank You!

[@BrianBDouglas]

Thanks so much for this comment! I appreciate it 🤗

[@ambers8804]

Best explanation I have ever seen about something so complicated. Amazing job

[@wagonlee5443]

That was excellent! Understandable and very well paced. I also appreciate the usage of MATLAB for examples in this series.

[@user-pf3cu4lo7u]

Extremely helpful explanation and visuals. Thanks.

[@krillansavillan]

really sick!

[@MsIvanz]

Could you include explanations of how sonars in-water work in your next videos? Can we apply a similar equation for signal processing from underwater sonars?

[@ptsdon]

I am hoping I have correctly determined why 4 pi cubed is used in the formula. I believe that it is the area of the spheres multiplied together from the transmitted signal, the reflection of the surface area of the target, and the received signal from the target.
Regardless, I learned A LOT from this video. So, thank you!

[@BrianBDouglas]

One is from the expanding sphere out from the transmitter, one is from the expanding reflected sphere out from the target, and one is from the antenna gain which is a ratio of directed energy over the isotropy energy.

Awesome

[@KjartanAndersen]

Sadly Radar Toolbox isn't available for me. I'll see if it's available for Octave

[@Warvideos401]

Hi, cant wrap my head around that Aant = Rlambda/b x Rlambda/h or something. Where you get that? Its the A of antena like a×b ???

[@jeevanshastry3020]

14:56 isn't it G^2 ..in the numerator of the SNR equation???

[@BrianBDouglas]

Yes!! I left that off when I was writing. Good catch!
