.... on how to capture a radar image, I guess you would call it "slow scan" (that has no outputs) by placing a transmitting camera in front of the screen and sending live feed to a central point within a 25 mile range to be viewed. This would be a mobile/moving radar (like in a car/van/SUV). I would need the transmitters, receivers, camera's, repeaters, routers or whatever would be required. Once captured, I would want to not only view it but convert it to digital to save/record/store/route .....maybe someone has some ideas?
Here's what I know. I'm working at trying to balance two variables...bandwidth of the network versus quality of video passed. For the sake of argument, let's say I have 8 mobile systems with from one to three CRTs each. Ideally, I need to pass: 1. the highest quality video (it is probably possible to capture this prior to the CRT in some way) I can, 2. a data channel with system info (time stamp, pointing angles, target range, firing command, some binary switch positions) and 3. a voice channel. I think I have a handle on the requirements for the last two so I am balancing the quality of the video channels with the bandwidth of the transmission media to create a flexible robust mobile network. I know it can be done. I'm just ignorant of how to do it. I know there are some bandwidth saving algorithms around...often times a fairly large part of a video image does not change from frame to frame. But maybe this doesn't matter. Maybe there is (or soon will be) enough bandwidth in a "cell phone-like" system that I don't need to worry about this. Anyway, I'll link my 8 mobile systems to a remote node, then put data from the systems on the internet in a secure fashion and send it back to central location for processing. The processing consists of taking the time stamped system data (radar pointing angles and range...a point in space) and comparing it to time stamped lat/long and altitude from "aircraft of interest" data received through a separate data channel. The video data gets displayed so that local experts can analyze what's taking place in the engagement and at the same time it is also stored for future playback. The voice channel allows monitoring of radar operator actions and some coordination among all the mobile systems, although they have an existing channel for this. The voice channel will also provide a broadcast system from the remote location for test/training organization. This is the stressing case. A slightly different one is when the systems are not mobile and situated on fixed concrete pads within a few hundred meters of each other. For that case, I just run fiber and I can get all the bandwidth I want. Thanks for the help,I look forward to your reply's David Rogers, KD4KOB Yahoo!
