摘要：

A new CYclone Global Navigation Satellite System (CYGNSS) data product is generated using all the available raw Intermediate Frequency (IF) tracks. In so doing, calibrated Delay Doppler Maps (DDMs) are produced using the CYGNSS raw IF processor, and the CYGNSS End-to-End Simulator (E2ES) to generate Look-Up-Tables (LUTs) to bin-by-bin correct the whole DDMs. Such calibrated DDMs are delivered with shorter incoherent integration time (N-inc), finer delay and Doppler resolution, and a wider range of delay and Doppler values as compared to the L1b CYGNSS data product, currently available in the Physical Oceanography Distributed Active Archive Center (PODAAC). This work aims to foster the use of this new data product, so as to improve the performance of CYGNSS for a wide range of scientific applications over land and ocean.
