Evaluation of Ground-to-Ground Jamming Utilizing Radio Set AN/ALQ-3(Xa-1).

摘要

The results of ground-to-ground jamming tests utilizing the radio set AN.ALQ-3(XA-1) are set forth. These tests were conducted to obtain information on and parameters for ground-based jamming of ground-based radars. The test results indicate that line-of-sight jamming of ground based radars can be accomplished by jammer equip ment of the AN.ALQ-3(XA-1) type up to a range of 26,000 yards. This jamming range can be obtained for both main and side-lobe jamming. However, emplacing the radar in defilade or utilizing available terrain masking precludes this effect iveness. In the modulation tests, random noise proved to be the most effective under all condi tions. Tone modulation at the conical scan fre quency of the target radar can be effective if the exact conical scan frequency of the radar is known. (Author)
