Documentation in this report was provided by the Instrumentation Division, Technical Services Directorate for a jungle penetration fuze program. The Fuze Research Engineering Division of Picatinny Arsenal requested height- of-burst HOB measurements in a jungle environment for an electronic fuze incorporated in a supersonic rocket. A sound-ranging system, successfully developed and fabricated in 1967 by the Technical Services Directorate at Picatinny Arsenal, was utilized with some modifications of acoustic sensors and amplifiers. The accuracy of the HOB data received by this system can optimally be plus or minus 5 based on evaluations at Picatinny Arsenal and Aberdeen Proving Ground. This accuracy depends on precise operator measurements in system setup and data reduction procedures, monitoring meteorological conditions in real time and monitoring sound velocity in real time. The details of a successful approach to HOB of supersonic rockets as determined by these fuze tests are included in this report together with the HOB test data and results. In these tests two electronic timing fuzes were compared in a jungle environment no discernable difference between their performance was measured.
