Surveillance capabilities and operational requirements for future Space-based radar systems are considered. With special attention paid to Air Traffic Control applications, an optimal system architecture is defined. The resulting large antenna dimensions call for novel solutions such as distributed arrays in space.

The detection problem of fluctuating radar targets in the presence of interference (noise and clutter) is considered; the assumed model for both target and clutter is a zero-mean stationary Gaussian random process with assigned power spectral densities. The pertaing optimum linear processor, namely the Optimized Filtering, is derived and its performance are evaluated in different operating conditions, including mismatching with the designed model. Finally, comparison with filtering techniques designed for targets with zero spectral width, i.e. the Moving Target Detector, are performed.
