A number of generic products have been developed for naval ESM systems. These operate on pulse widths from 50 nanoseconds and offer excellent linearity and tracking. All Filtronic DLVA's exhibit excellent performance tracking, greatly reducing the need for calibration of the overall receiver. IF phase receiver and downconverter, is intended as an adjunct to amplitude comparison systems and allows the system designer to achieve interferometric bearing performance in a cost effective manner.
Users report bearing accuracy of fractions of a degree in a calibrated system.
The unit is compact enough for masthead operation. The DR016 is a high accuracy device operating 2-8 GHz with 14 BIT resolution available for output as raw data to the system processor at a 40 MHz clock rate. A range of products are available for naval jammers employing repeater and deceptive jamming techniques. Storage is achieved by re-circulating the RF pulse around a coaxial delay line containing sufficient amplification to sustain the pulse. The RA002 is currently in use with navies in four countries.
