Performance Comparison of Reflector- and Planar-Antenna Based Digital Beam-Forming SAR

<table>Timing (diamond) diagram for an orbit height of 650 km and a transmit duty cycle of 8%. For a given <i>PRF</i> the diagram shows the restrictions on the receive window due to transmit instances (wide dark strips) and nadir echos (thin light strips).</table>
