Target point recognition in aerial lobe - uses correlator for processed monopulse values, consisting of digital transit time chain with comparators and integrators

摘要

The monopulse processor is intended for application in target point recognition which evaluates a signal concerning the target point in the aerial lobe, in addition to the time coded SSR-input signals. The recognition takes place even in garbling situations. The process is carried out in the following steps: the processed monopulse values are fed into a correlator, consisting of a digital transit time chain with comparators and integrators. A reference is formed from two scanning values obtained from a certain given target distance. The reference pulses are compared with information pulses and a tolerance value, and are used for integration of the monopulse values. The correlated values are stored in a memory at the beginning of a frame. The monopulse processing contains derivation of monopulse signals in high and intermediate frequency range, as well as signal processing in the video range.
