Abstract
A memory system for histogramming the pulse descriptor word output of a radar warning receiver for initial processing of the received data for quickly determining the numbers and types of emitters in the system's environment. The disclosed apparatus histograms the number of pulses received in a given time interval versus scaled values of frequency and time differences of arrival plus it assigns available memory locations only when confirmed data is received. A typical histogram size of 1,024 (radio frequency) by 8,192 (time difference of arrival), or 8,388,608 pixels is disclosed along with comparisons and contrasts with less efficient conventional histogramming arrangements.
