A novel technique for rejecting clutter residues is proposed. The technique uses maximum-likelihood estimates of the target Doppler and target amplitude generated from consecutive pulses out of an MTI (moving target indicator). Multiple estimates are made and consistency checks are applied to the estimates. Simulation results indicate that for large clutter-to-noise ratios (>or=55 dB) the probability of false alarm from clutter residues is reduced from 1.0 to below 0.01.<>

Synchronization techniques used in the Bistatic Alerting and Cueing (BAC) program are examined. Particular attention is given to illuminator search, target search synchronization, RF synchronization, PRF (pulse repetition frequency) synchronization, range gate synchronization, and solution of the bistatic triangle. All of the synchronization techniques have been implemented and tested during the two-and-a-half years of field-test demonstration of the BAC system. It is concluded that feasibility testing produced excellent results.<>

The US Naval Weapons Center (NWC) X-band active array system was created for the purpose of exploring active array system technology. Among the key features of the NWC Active Array Demonstration Unit (AADU) is the inclusion of a microprocessor behind each of the forty elements in the array. With the ability to do processing at the element level, the AADU has flexibility for investigating a variety of distributed beam control techniques. The calibration, beam control, system interfacing, and system speed of the AADU are examined.<>
