A feasibility study of rain radar for the Tropical Rainfall Measuring Mission. IV - A discussion of pulse compression and adaptive scanning
Abstract
The possible use of a pulse compression system on the Tropical Rainfall Measuring Mission to meet the requirement on the number of independent samples for the rain radar under the constraint on allowable power consumption. The applicability of a pulse compression system to the mission depends on the technological feasibility of reducing the range sidelobe levels of the strong surface echo down to at least -60 dB. It is found that applying the pulse compression technique to the mission is risky. The concept of adaptive scanning is examined, and its power saving efficiency is numerically evaluated for four kinds of rain searching schemes. It is shown that the power saving efficiency of adaptive scanning is considerably high for all the rain searching schemes evaluated.
