Abstract

Abstract:

Based on the wide beam antenna radar level meter,an improved algorithm for wide beam linear array radar level meters is developed to solve the problem that the detection performance of wide beam antenna radar is extremely vulnerable to the strong background clutter.For a uniform linear array frequency modulated continuous wave radar,the first step of the algorithm consists of the detection of strong scattering points through range and estimation direction of arrival for strong scattering points;the second step is the recognition of efficient points from strong scattering points set on the basis of analyzing the production condition of strong scattering points.The measurement value was obtained from the efficient points set.A set of field experiments was conducted in a grain processing factory with a 77 GHz wide beam linear array radar level meter.The proposed algorithm can achieve an accurate and steady measurement of the low-dielectric constant material level in harsh industrial conditions.This study does away with the restriction of beam width,which is of great significance for the popularization and application of miniaturized,low-cost wide beam radar level meters.

Key words: level measurement, wide beam, clutter, strong scattering point, level meters
