AN UPWARD PULSE DELAY SYSTEM FOR MEASURING ELECTRON DENSITIES OF THE IONOSPHERE

Abstract

A system is described which measures the free electron content of the Ionosphere by the transmission of rf pulses between a rocket, which is passing through the Ionosphere, and the ground. The basic requirements and operation of the system as a whole are examined. The development and design of each of the component parts of the system are then discussed, including circuit diagrams and any important construction details. Special emphasis is placed on the design of a ground based low frequency pulsed transmitter. The design of a low frequency rocket-borne receiver also capable of operation from 4 to 12 mc is discussed in detail. The receiver is completely transistorized and incorporates a unique gated AGC system which greatly improves the signal to noise ratio in the receiver output. A ground station for receiving and recording the pulses transmitted from the rocket is also described including the circuit design of the various units.
