Control of emitted electromagnetic radiation

Because an imaging radar is an active system, the properties of the transmitted and received electromagnetic radiation (power, frequency, polarization ) can be optimized according to mission specification goals.

The top part of the image shows a three band combination (P-Band-->RED, L-Band-->GREEN and C-Band-->BLUE) for JPL aircraft SAR overfly over Landes (F) during the MAESTRO-1 campaign. On the bottom side, a multipolarization combination (HH -->RED, VV-->GREEN and HV-->BLUE) shows different details of the same site.
