Application of Bistatic Doppler Weather Radar to Wind Observation in Precipitation Systems

The concept of bistatic Doppler weather radar and its application to wind observation in precipitation systems are introduced.The bistatic radar can measure the radial velocities in different directions simultaneously with less expense and maintenance.The data from bistatic radar can be used in analyzing the three dimension wind in precipitation system.But the bistatic radar has a short range coverage and is sensitive to contamination from transmitter sidelobes and secondary scattering from weather echoes due to the passive and low gain antenna.In addition,the radar needs rigid frequency and time coherences.The bistatic radar technology is a potential tool in meteorology.
