Hey all! I am wondering if anyone can try and give me a rough idea on how a transceiver on a let's say a fish finder interprets echo returns.
I apologize for my rough sketches that were done on my iPad.
When a echo bounces off something and is returning to the receiver, is it one large echo that gets measured in size? Or a bunch of little echoes returning?
How does the receiver even get all the returns within its cone angle when the signals are getting sent out on oblique angles.
And last thing.
A top down view looking down the cone of a transducer would look like this with fish under it.
Most fish finders give you a side view like this...
Can transducers calculate echoes to display them on a screen in way where it actually looks like a top down view? Or can transducer not calculate the distance between objects in a top down view in returned echos.
If anyone could help me comprehend these things a little better it would be appreciates.
