Abstract : An aircraft landing system which provides a pilot a perspective view of a runway on which he intends to land under zero visibility conditions. The system includes a multiplicity of microwave transmitters spaced at known intervals along both sides of a runway and a timing generator which causes the microwave transmitters to transmit in sequence. The aircraft contains a monopulse receiver which provides conventional azimuth angle video information to a CRT display and also provides range video information to a Y sweep generator. The latter Y sweep generator generates a sweep voltage for the Y axis of the CRT display which is of sufficient length to display all transmitted pulses from all microwave transmitters in sequence with the correct relative spacing between microwave transmitters.
