One of the main tasks of the maritime patrol radar is detecting small targets on the see surface during search and rescue (SAR) operations. The radar cross section (RCS) of life-boat is at the level of several square meters (0-6 dBsm), and the RCS of the rescuer is much smaller than 1 m2 (-10-0 dBsm). The sea clutter level strongly depends on sea state and varies from -30 dBsm for calm sea to 10 dBsm for high sea state (for typical, middle resolution, maritime radar). The classical design of maritime patrol radar does not allow sub-clutter visibility, required for rescue operations in bad weather conditions. The paper presents the idea of joint optimization of radar operation modes, radar detector and tracking unit to obtain low false track probability and very high sensitivity necessary for SAR operations.
