Motion Compensation for Long Integration Times and DoA Processing in Passive Radars

In this work, a multistage target motion compensation solution for long integration times and the direction of arrival processing in geostationary-satellite-based passive radars is presented. Long intervals are considered to compensate associated propagation loss, but during time dynamics can extend backscattering more than one range or Doppler cell. To control gain-processing reduction, combination detection, tracking, feature extraction, filtering techniques designed provide automatic adaptation each unknown dynamic area interest. The proposed methodology validated with real data acquired by radar demonstrator developed University Alcalá (IDEPAR), results confirm that monitoring exploiting digital video broadcasting-satellite (DVB-S) signals clearly improved.
