ADVANCED DIRECTION FINDING TECHNIQUE

RADIO DIRECTION FINDING IS A VALUABLE PASSIVE INTERCEPT TECHNIQUE THAT CAN PROVIDE CRITICALLY IMPORTANT DATA WHICH MAY INFLUENCE THE OUTCOME OF A MILITARY ENGAGEMENT. CONVENTIONAL ANTENNAS FOR DF ARE NARROWBAND AND PHYSICALLY LARGE IN THE HF AND VHF BANDS. ENHANCING THE PERFORMANCE OF SMALL ARRAYS REQUIRES LARGE, COSTLY DIGITAL COMPUTERS WITH THE CAPABILITY OF EXECUTE COMPUTATIONALLY INTENSIVE SIGNAL PROCESSING ALGORITHMS. ASTRON CORPORATION PROPOSES AN INNOVATIVE DF ANTENNA SYSTEM THAT IS BROADBAND, HIGH DYNAMIC RANGE, SENSITIVE, ACCURATE, AND PHYSICALLY SMALL ENOUGH TO BE USED ON MOST DEPLOYMENT PLATFORMS AT VHF AND EVEN HF FREQUENCY BANDS.
