Abstract

A passive electronic warfare system must deinterleave trains of pulses from a number of radar transmitters. An adaptive parametric channelizer for acquiring and tracking trains of pulses consists of an input channelizer operating under the control of a resource control processor. Each pulse descriptor word (PDW), a set of digitized signal parameters measured by a specialized receiver of radar pulse signals, is temporarily stored in a first-in-first out (FIFO) buffer memory.
PDW data from the FIFO buffer memory is then applied to a set of parameter filter devices. These filters are provided with a range of parameter values, forming windows, by the resource control processor. The filters operate such that when a PDW
falls within one of the filter s windows, a match output is asserted and applied to a match list generator which maps asserted matches into a list of filter index numbers. That list is applied to a mapper which transforms filter indices into track buffer indices in order to store a PDW that matches one filter into an associated track buffer of a set of track buffers. The combination of at least one parameter filter linked by the mapper with a track buffer form a track channel.
The match list generator supplies data and event interrupts to the resource control processor which causes the parameter window of any track channel to be modified and force track channels to be merged.
