Can you, or anyone else, give us an example of how a lidar gun works, not in the physical layer (I use computer networks terminology), but in the application layer. I would like to see the algorithm used to acquire speed and how it detects jamming, if possible for the 2nd one.
I would like to have the whole picture in more details and the time to search magazines (ex. IEEE) for methods etc it's just out of the question as my time is limited.
I believe they just don't use contiguous pulses = many measures, so they create a D = D(t) diagram = speed. One manufacturer uses groups of 3 or 4 pulses, others uses 2 etc. After they receive the reflections = data, how they process them ? What stages they follow to give speed + jam code ? How they distinguish jamming pulses from real pulses ? A simple and easy example (let's say from an older lidar gun) would be perfect.
Difficult and technical questions, but it's a good time to review my DSP knowledge. If there is a book or pdf or site or magazine easily accessible from university libraries (IEEE, Springer etc) I can easily read it, even give a short abstract to all other users. I just don't have the time to search on my own.
Thnx for your time and sorry for being difficult sometimes.
Today, it's the day the Italian forces invaded Greece back in 1940 and it's a national feast. So, I would like to wish, not even a single person in this planet would have to experience the consequences of a war ever again.
