Several CPM modes along with BPSK are compared as for the signal delay estimate potential accuracy, spectral resources being tightly limited. MSK is demonstrated to have an energy gain versus BPSK according to the delay measuring accuracy criteria up to 10 dB and more.
We propose a concept of the utilization of an aircraft Doppler Navigation System (DNS) as a sea-surface wind sensor complementary to its normal functionality. The DNS with an antenna, which is non-stabilized physically to the local horizontal with x-configured beams, is considered. We consider the wind measurements by the DNS configured in the multi-beam… (More)
We suggest a conceptual approach for measuring the near-surface wind vector over water using the airborne weather radar, in addition to its standard meteorological and navigation applications. The airborne weather radar operates in the ground-mapping mode in the range of high to medium incidence angles as a scatterometer. Using the aircraft rectilinear… (More)
