Abstract
The disclosure teaches a method, and an apparatus for carrying out the method, for determining the time between TO and FRO received waveforms from the time reference scanning beam (TRSB) of a microwave landing system (MLS). In accordance with the invention, the time interval between the TO and FRO received waveforms is determined by correlating the received waveforms with apriori waveforms representative of the TO and FRO waveforms respectively. The apriori waveforms are generated by having a process construct matched filters for these waveforms. A FRO received waveform is used to provide an apriori representation of a TO received waveform and vice-versa. In one embodiment of the invention, the TO and FRO waveforms which are used to construct the matched filters are time reversed.
