The electromagnetic compatibility of RASS techniques under the airfield conditions

The solution of the electromagnetic compatibility problem for radioacoustic atmospheric sounding equipment in the airfield conditions by using a special quasi-continuous condition is discussed. Namely, the sounding acoustic parcels are illuminated with radio impulses of a triangular pulse envelope form, and the spatial fronts duration providing the coverage of the whole working height interval. In the sounding height interval of about 500 m, the active spectrum-width of radiated radio signals is only 0.34 MHz, i.e. approximately five times less than that of short rectangular radio pulses. The sounding height measurement is made via acoustic channel with the margin error not worse than 0.8 %, the sound pulse parcels spatial duration is 30 in. Such radioacoustic techniques can be placed in immediate proximity to a runway in order to control mesoscale weather phenomena, dangerous for aircraft.
