Summary

Description

<p>The proposed work focuses on the evaluation and testing of the W-band SSPA on the current airborne Cloud Radar System (CRS) transceiver so that it can be operated with either the original Klystron-based transmitter, or the SSPA. We will swap in either transmitter to maintain the current EIK capability. As we gain more confidence in the SSPA-based transmitter, we will migrate entirely to this approach.  This SSPA-based transceiver will enable the usage a number of recently developed radar techniques, such as advanced versatile Tx/Rx waveform, ultra-low sidelobe pulse compression, and frequency diversity.  It is necessary to modify the hardware and firmware in order to accommodate the above new techniques. Recent advances to HIWRAP’s advanced waveform generation need to be transferred to CRS to take full advantage of the SSPA. The resulting work is readily applicable to upcoming cloud and precipitation radar spaceborne missions.</p><p> </p><p> </p>
