Attenuation of radar waves by rain in India

Rainfall in India considerably attenuates the Radar Waves in 3cm. band. The decrease in the target range of an air force radar has been estimated for the type of rainfall common in most parts of India and a comparison is made between ranges obtained in 3 & 5 cm. bands. It is suggested that an all weather or reconnaissance radar working in the X-band will be very unsatisfactory during monsoons in India
