How does a Doppler radar differ from a traditional weather radar?
Traditional radar like a maritime Radar works by transmitting energy at a storm and receiving the back scatter from rain, the antenna maybe angled upwards and the colouring of the radar image may become coloured, and is probably an add on mode so maybe horizontally polarised. Doppler weather radar is vertically polarised as it is looking for wind sheer effects from move rain drops moving up wards and down wards in storm clouds system. Doppler system can still detect the picture that the traditional weather radar can by peak summing the Doppler bins for each range cell in a range Doppler map. However the Doppler system will have better signal to noise then the Traditional system as the system is coherent and dose not relay of lossy filter based on statistical differences of a target distribution and rains distribution.
