A method for performing binary integration of fixed cell radar alarm data. n order to determine whether M cell alarms have occurred in the last N processing intervals a memory is provided which is N bits wide by K words long, where K is the number of cells. Binary 1's are placed in memory positions corresponding to timing intervals at which alarms have occurred and binary 0's are placed in positions corresponding to timing intervals at which alarms have not occurred. A serial comparison with a register having M bits stored is made to determine which of the words contains at least M binary 1's.

Binary integrator for fixed cell radar alarm data

A method and apparatus for modifying data which is stored in a medium of hival quality. The original data is left unmodified, and a modification document is prepared which has addition and deletion data thereon. The original and modified data is combined in a given way to generate a correctly modified composite.
