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!
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.
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?
This is by far the best explanation of radar - great detail and simple enough for anybody to grasp. Thank You!
Thanks so much for this comment! I appreciate it 🤗
Best explanation I have ever seen about something so complicated. Amazing job
That was excellent! Understandable and very well paced. I also appreciate the usage of MATLAB for examples in this series.
Extremely helpful explanation and visuals. Thanks.

Thank you so much for sharing the knowledge
You're welcome, glad you found it helpful!

Sadly Radar Toolbox isn't available for me. I'll see if it's available for Octave
really sick!
Excellent presentation. How can we get a copy of this Matlab app?
14:56 isn't it G^2 ..in the numerator of the SNR equation???
Yes!! I left that off when I was writing. Good catch!
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 ???
Awesome
