1) You can't really generate an image like a camera does using radar. It depends on the resolution of the radar and the number of data points you get from the radar system. You might see an object as a collection of many points if your radar is good enough. This is enough for electronics systems to make decisions on.
2) Chirp interference is an issue with FMCW radar, and there are also security concerns with hostile jammers putting vehicle occupants at risk. Uhnder is a company working on digital radars. They use a digital sequence called a spreading code to encode the RF signal being transmitted so that each one has a unique signature that is only known to a car. It improves interference issues and prevents hacking. I write about a bit of this here:
Also one more question: Is there some encoding involved. As there would be many source of chirp emitting same frequency range and BW, from different direction. Can this interfere with RX?
How could we generate an image of the object in sight using radar(As it was shown).
A single chirp signal would be giving an information about a single point in space from where it is reflected, how do we map full object.
Both great questions.
