Several concepts have now been published for geosynchronous synthetic aperture radar (GEO SAR). The long distance means that to achieve a satisfactory signal to noise ratio, the signal integration time may be minutes or hours. Over this period the atmosphere cannot be assumed static and phase compensation for atmospheric perturbations is needed. A simulator has been developed to quantify the performance...
Radar entomology has developed such that routine long-term monitoring of insect flight through the atmospheric boundary layer is now practical. Typical entomological radars use X-band (9.4 GHz) marine transceivers with a vertical pencil beam and rotate the plane of polarisation about the beam axis. Ideally, insect species and other parameters (mass etc.) should be estimated from the measured radar...
