Abstract
A multi-mode pulsed radar method for sensing or measuring a product material in a storage tank includes providing a measure of radar signal attenuation for pulsed radar signals transmitted to the product material. Automatic adjustment of one or more transmitted radar pulse parameters is implemented by selecting a pulse width and a pulse amplitude based on the measure of radar signal attenuation. In signal mode 2 higher amplitude and/or wider pulses are selected when the measure of radar signal attenuation is relatively high and in signal mode 1 lower amplitude and/or narrower pulses are selected when the measure of radar signal attenuation is relatively low. The radar pulse is transmitted to the product material using the selected pulse width and the pulse amplitude. The target signal reflected or scattered from the product material is processed to determine at least one parameter, such as product level.
