CW Doppler Radar Block Diagram: A simple CW Doppler Radar Block Diagram, such as the one shown in Figure 16-14, sends out continuous sine waves rather than pulses. It uses…
Phased Array Radars: Phased Array Radars - Introduction With some notable exceptions, the vast majority of radars have to cover an area in searching and/or tracking, rather than always being…
Frequency Modulated Continuous Wave Radar: The greatest limitation of Doppler radar, i.e., its inability to measure range, may be overcome if the transmitted carrier is Frequency Modulated Continuous Wave Radar.…
Radar Beacons: A Radar Beacons is a small radar set consisting of a receiver, a separate transmitter and an antenna which is often omnidirectional. When another radar transmits a coded…
Moving Target Indicator Radar Block Diagram: Basically, the Moving Target Indicator Radar Block Diagram compares a set of received echoes with those received during the previous sweep. Those echoes whose…
Pulsed Radar Systems: A Pulsed Radar Systems is generally required to perform one of two tasks: It must either search for targets or else track them once they have been…
Radar Performance Factors: Quite apart from being limited by the curvature of the earth, the maximum range of a radar Set depends on a number of other Radar Performance Factors.…
Submarine Cables: Submarine cables use principles very much like those of coaxial cables. Thus they are coaxial, have repeaters and equalizers and have dc power fed to them, with opposite…
