markejackson02 Posted July 20, 2016 Report Share Posted July 20, 2016 Do all airborne radar sets work on the same frequency? If so, do they interfere with each other? I imagine it's not an issue as they are probably only constructed to receive if they are transmitting. If it could receive without transmitting, would that permit a set to "see" a storm without transmitting using other sets' reflected energy?

carusoam Posted July 20, 2016 Report Share Posted July 20, 2016 Expect.... Kind of like using a taxi/landing light... You might see other landing lights by other people, but making use out of their light will be unlikely..? if your scope all of a sudden gets really bright, is something with radar coming right at you? (Light at the end of the tunnel?) The amount of energy emitted and sensitivity of the receiver are going to be economically limiting. a lot of radar systems emit a known amount of energy and measure what gets returned. Without knowing what was being sent by the other system, it would be difficult to use the data that is being returned. Strength of the echo vs. no return.... thoughts that come to mind, -a- Quote Link to comment Share on other sites More sharing options...
Piloto Posted July 20, 2016 Report Share Posted July 20, 2016 Most airborne radar operate on X band (10GHz). Some large aircraft radars operate on C band (5GHz). Most operate on the same frequency as others because they are made from the same manufacturer. But there is no interference from other aircraft because the radar reception period is synchronized to its transmission sequence and antenna angular position. On some occasions you may see other airborne radars (dots) but for a very short time. José 2 Quote Link to comment Share on other sites More sharing options...
N201MKTurbo Posted July 20, 2016 Report Share Posted July 20, 2016 Radars use a method of time gating the transmitted and received signals plus time shifting of those pulses to discriminate its own pulses from noise including other radars. Some also use polarization discrimination. The reflected energy will shift in polarization from the transmitted energy. This was one of the early challenges of designing a radar system and was solved long ago. Modern digital electronics makes the pulse gating method very easy to implement. 1 Quote Link to comment Share on other sites More sharing options...
