The original monopulse tracking radars suffered in antenna efficiency and complexity of microwave circuitry because waveguide signal-combining circuitry was a relatively new art. These problems were overcome and monopulse radar, with modern compact off-the-shelf processing circuitry, can readily outperform scanning and lobing systems. The monopulse technique also has an inherent capability for high- precision angle measurement because its feed structure is compact with short signal paths and rigidly mounted with no moving parts. This has made possible the development of pencil-beam tracking radars that meet missile-range instrumentation-radar requirements of 0.003° angle-tracking precision.

Conical scanning is a method used to ...
