MODEL-BASED ECHO CURVE PREDICTION FOR PULSED RADAR

摘要

A method of modeling a pulsed radar gauge (PRG) that includes a transceiver coupled by a process connection to a probe installed on a tank having at least one product material therein. A mathematical model is provided that includes (i) dielectric properties and dimensions of materials used in the process connection, (ii) at least one tank dimension, (iii) dielectric characteristics of the product material, and (iv) a probe length. Using a processor implementing a stored echo prediction algorithm that utilizes the mathematical model inputting pulse characteristics including a shape of an input radar pulse launched by a transmitter of the transceiver onto the probe into the mathematical model, and generating a predicted echo curve from the mathematical model.
