ADAPTIVE RADAR SYSTEM WITH MUTLIPLE WAVEFORMS

摘要

A pulsed radar method of sensing or measuring a product material in a storage tank. A plurality of waveform types are automatically selected based on a power limitation. The pulsed radar signal is transmitted by a programmable transmitter to the product material, wherein the pulsed radar signal is reflected or scattered by the product material to provide a radar signal during an interval of time including a target signal. An initial gain or attenuation is automatically set for a programmable receiver. The programmable receiver receives the radar signal including the target signal during the interval of time, and the target signal is signal processed using a lower attenuation setting as compared to the initial gain or attenuation to determine at least one parameter associated with the product material. The transmitted and received radar signal can also be adjusted according to the measured SNR.

1. An adaptive pulsed radar method of sensing or measuring a product material in a storage tank, comprising:
adaptively and automatically selecting between a first of a plurality of waveform types based on a power limitation for an adaptive pulsed multi-waveform radar system having a programmable receiver (Rx) and a programmable transmitter (Tx) implementing said method; automatically setting an initial gain or attenuation for said programmable Rx; transmitting a pulsed radar signal using said first waveform type to said product material, wherein said pulsed radar signal is reflected or scattered by said product material to provide a radar signal during an interval of time including a target signal; said programmable Rx receiving said radar signal including said target signal during said interval of time, and signal processing said target signal with a lower attenuation setting compared to said initial gain or attenuation to determine at least one parameter associated with said product material.
