Operative determination of soil moisture by airborne microwave radiometric equipment

Özet

The intensiy of the soil's microwave radioheat emission is described by its radio-brightness temperature which is measured by mecrowave radiometric devices. The experimental studies on board of an airplane-laboratory were performed above two test firing grounds. Synchronously with the airplane remote sensing measurements, samples for determination of soil moisture were taken from the surface (upto 10cm) layer at every 250 m.
