Abstract

POLAR MESOSPHERIC SUMMER ECHOES (PMSES) ARE VERY STRONG RADAR ECHOES PRODUCED BY ELECTRON DENSITY FLUCTUATIONS AT HALF THE RADAR WAVELENGHT (BRAGG SCATTER CONDITION) IN THE ALTITUDE RANGE 80-90 KM. THE TEMPORAL BEHAVIOR OF PMSE RESPONSE TO HIGH-FREQUENCY PUMP HEATING CAN BE EMPLOYED TO DIAGNOSE THE CHARGED DUST LAYER. SPECIFICALLY, THE RISE AND FALL TIME OF RADAR ECHOES AS WELL AS RELAXATION AND RECOVERY TIME AFTER HEATER TURN-ON AND OFF ARE DISTINCT PARAMETERS THAT ARE FUNCTIONS OF RADAR FREQUENCY. THE MAIN PURPOSE OF THIS STUDY IS TO USE THE TEMPORAL EVOLUTION OF PMSES DURING ACTIVE MODIFICATION USING HIGH POWER RADIOWAVES TO STUDY THE FUNDAMENTAL PHYSICS OF DUST CHARGING IN SPACE AND TO DEVELOP A NEW REMOTE SENSING TECHNIQUE FOR MEASURING IONOSPHERIC PARAMETERS IN THE NEAR-EARTH SPACE ENVIRONMENT.
