ABSTRACT:
A within-pulse radar having an array of aerial elements each of which feeds signals to a storage filter via a frequency changing stage, in which the outputs from alternate filters are combined in one channel and the outputs from the remaining filters are combined in another channel which includes a switchable phase shifter which introduces a phase shift of 0.degree. or 180.degree. and which is switched during each pulse length, results in improved separation of scanning and grating lobes. The outputs from the two channels are combined for utilization.
