F. Radar and Optical Tracking.
Because of their limited range. ground radar sets and theodolites
were only of minor value in tracking balloons. Sets such as the
SCR-684, the SP.M-1, and MPS-6 are suggested when the balloon is
expected to remain within the 60 to 80 mile range.
VI. INSTRUMENTATION
A. Altitude Determination
To provide accurate, sensitive and readable records of the pressure
(altitude) encountered by the balloon, various systems have been
tried. A modified radiosonde-type aneroid pressure capsule (Signal
Corps ML 310-/) has been the basic sensing element, but three
different systems of modulation of the radio signal as a function
of pressure have been used.
(1) Standard Diamond-Hinman Radiosonde Pressure Modulator
Seen in Figure 29, the standard Diamond-Hinman radiosonde system
