The PRED-3 PRI Predictors combine real-time pattern recognition with advanced algorithm design to adaptively acquire and track radar pulse repetition interval patterns.

MCCM's proprietary algorithm has shown to be effective in establishing an initial estimate of a PRI sequence from a small number of received pulses. This estimate is subsequently refined as additional pulses are received, until the actual pattern has been found and verified. Using this approach allows jamming to begin sooner in the engagement and leads to a higher probability of success.

The PRED-3 has been designed to work with a variety of PRI patterns. These patterns include constant, dwell shift, sliding PRI, sine, jitter or staggered, with pattern lengths in excess of 128 positions. 

The PRI prediction board is a PC/104 form format. By adding an auxiliary board of the same format, the PRED-3 can be made to track sine wave modulated PRI patterns.

The PRED-3 has built-in target generation capability for creating leading or lagging false targets anywhere in the PRI. Built-in technique generator functions include multiple false targets (from 1 to 255), range bin masking (RBM) and asynchronous pulse rate modulation (APRM). It can also track radar pulse doublets as a single pulse.

The PRED-3 is capable of working through signal fades caused by antenna pattern nulls, effective jamming or receiver blanking. It can use time gating to eliminate interfering pulses and prevent the DRFM memory from being overwritten by these extraneous pulses. With a frequency word input for each video pulse, the PRED-3 can implement time sharing of multiple in-band signals by de-interleaving pulse trains and tracking them individually.

The compact size of the PRED-3 allows for easy integration into a variety of host system architectures – from lab to pod-mounted jammers.
