The same digital signal processing techniques used for improving the reliability of communications can be applied in a variety of areas, including active and passive RADAR, null-steering for anti-jam communications, and target recognition/tracking, among others.

For example, GIRD Systems is currently subcontracted on a program for the U.S. Air Force to develop DSP-based solutions for direction-finding. Direction-finding is used to determine the position of an RF emitter by processing signals from an antenna array. Analog RF direction-finding often requires time-consuming and expensive calibration due to correction for mismatch in the analog components.

By using digital signal processing, the customer will enjoy increased system flexibility and accuracy due to reduced calibration time and operational costs.
