To increase the radiated power of pulsed antenna arrays (PAR) of nanosecond and subnanosecond ranges, which are increasingly used in communication, location and electronic warfare systems, a method is used to increase the number of independent antenna modules containing an antenna and a less powerful generator, compared to a grating based on a single powerful generator. However, it became necessary to realize spatial synchronization of the signals emitted by these  modules.  In  these  ranges,  the  implementation  of  such  a  task  is  very  difficult,  due  to  the  fact  that  the  time  shift  of  the position of the pulses of the generators is approximately equal to the pulse width. To solve this problem, a synchronizer was  introduced  into  each  antenna  module,  described  as  a  discrete  automatic  parameter  stabilization  system  with  nonlinearity of the discriminating characteristic of a time-based discriminator of the relay type. The presence of jitter of the time position of the pulse emitted by the generator results in linearization of the discriminator’s relay characteristic, which made it  possible  to  apply  a  linear  model  of  the  synchronization  system  for  analysis  and  facilitated  the  determination  of  its parameters, such as the time of entering the synchronization mode, the capture and holding band, the static and dynamic errors of the time position of the pulse. Experimental PAR consisting of two and four elements showed the possibility of synchronization of signals in these bands and high quality of spatial alignment of signals. For the first time in the world, automatic  spatial  synchronization  of  the  time  position  of  nanosecond  and  subnanosecond  pulses  emitted  by  individual generators was realized, which confirmed the possibility of an almost unlimited increase in the radiated power of PAR in these ranges.
