Range Attenuation

</dt>
In radar terminology, the decrease in power density (flux density) caused by the divergence of the flux lines with distance, this decrease being in accordance with the inverse-square law. </dd>
For one-way transmission, this attenuation is proportional to 1/RE2 where R is the range from the transmitter. For a radar and a point target, the range attenuation is proportional to 1/RE4, the transmission being two way. [[/a>|/a> ]]
