Flood monitoring and forecasting are the key challenges to ensure the population safety. Modern spaceborne instruments significantly extend the capabilities of the terrestrial hydrological network, since they enable one to perform measurements over large areas. In 2014 the Japan Aerospace Exploration Agency (JAXA) launched spaceborne dual-frequency precipitation radar (DPR) and increased the possibilities...
The Global Precipitation Measuring (GPM) was proposed jointly by US and Japan and satellite equipped with a dual-frequency precipitation radar (DPR) and a microwave radiometer (GMI). GPM is partly a follow-on mission of the Tropical Precipitation Mission (TRMM), but GPM will extend the observation to cold regions. Our team has experience in developing of retrieval algorithms for precipitation radar...
Sea Winds scatterometer with an orbit altitude of 800 km was chosen as a prototype of the first Russian orbital scatterometer. A reduction of the orbit altitude to 650 km has brought about two competing approaches to the choice of swath width: either to remain the original 1800 km swath or the incidence angles by reducing the swath to 1500 km. The advantage of a wider swath is the best covering of...
Theoretical model for return waveform was developed for underwater ultrasonic sonar with wide antenna beam at vertical sounding. First time the analysis of return waveform was used in acoustic system for measurement of significant wave height as in radio altimeter. New retrieval algorithm was developed for scheme of measurement and the advanced underwater acoustic “altimeter” can measure the significant...
