Abstract
The decoding circuit of the invention comprises essentially a digital filter 16, a pulse-width recognition circuit 17 a pulse peak amplitude selection circuit 23 and a circuit for decoding MLS boosted scanning pulse pairs 32 to 38. This decoding circuit makes it possible to eliminate parasite pulses from a clutter source whose width is incorrect when compared to the width of useful pulses and also to eliminate pulse pairs that have the right width but do not have the right interval.
