Investigation and experiment of radar systems in unmanned aerial vehicles

In recent times, there is a growing interest in radars used by Unmanned Aerial Vehicles (UAV). These radars in UAVs are used for a variety purposes such as surveillance & reconnaissance, interferometry, foliage penetration, environmental monitoring, moving target indication, etc. However, the...
