A calibrated waveguide directional coupler was mounted prior to the horn antenna to monitor the peak and mean powers. Whole-body SAR was measured using a pair of monkey bag models filled with simulated muscletissue and twin-well calorimetry. Localized SAR was measured by inserting three small plastic cannulae and MW-compatible temperature probes in the head and the neck of the model. In addition, a saline filled 3-liter plastic bottle, approx. the size of the monkey, was used to measure SAR in the monkey chair prior to exposure.

Distance between exposed object and exposure source
A description of the setup and operation of Stanford linear energy doubler (SLED) pulse-forming devices has been presented elsewhere [Farkas et al., 1974, 1975]. SLED pulses were only created when the resonant cavities on the SLED were tuned to 5.62 GHz; otherwise, the radarpulses passed through unamplified.
