A1. “ADF interference blanker development,” M. M. Newman, IRE ON Aerospace and Navigational Electronics, vol. ANE-5, pp. 86–91; June, 1958. Pubi. Abst. — Interference blankers have been developed to give improvement ratios of the order of 1000 in the presence of severe precipitation static of the order of 150,000 pulses per second. Recently the blanking technique has been applied to ADF receivers with the objectives of simplification, reduced size and weight, improved sensitivity in the presence of interference, reduced intermodulation distrotion, maintenance of the relative phases of the sense and loop signals, and general compatibility with ADF receiver operation.
