Abstract
Results of experimental investigations into the effects arising in the detection and ranging of the earth's forest cover with the use of pulse ultrabroadband radio-frequency radiation are described. A narrow-beam transmitting and receiving antennas oriented at a sliding angle to the forest canopy were mounted on a special mast at an altitude of 21 m above the ground. A corner-cube reflector was used to align and to calibrate the measurement system. The results obtained are compared with the data of independent biometric measurements.
