In studying electromagnetic propagation through the exhaust flames of reaction motors, the need of improved instrumentation for determining the loss of energy in the flame was recognized. A system utilizing pulsed electro-magnetic energy at S-, X-, and K-Band frequencies on a time-sharing basis has been constructed and used in the field to make such measurements. Lens antennas were used to focus the energy within the flames and a traveling frame provided a means of exploring the length of the flame. Data was recorded on film at the rate of 32 readings per second for each frequency. This system Is here described the measurements obtained will be given In a later report.
