Abstract

In this paper, a clutter suppression algorithm for velocity measurement of water flow signals is presented to improve the signal-to-noise ratio. Considering the characteristics of water flow signals and the properties of moving target indication (MTI) algorithm in signal processing, we use Texas Instrument's IWR1843 development card and DAC1000 acquisition card for data acquisition and apply the Doppler frequency shift of the signal as a reference to solve the problems encountered in MTI. First, we perform distance-dimension FFT to extract the distance unit where the target is located. Then, MTI is used to eliminate static clutter. Finally, we define a kind of adaptive weighted sliding window based on the Doppler frequency shift to suppress the abnormal growth of spurious signals after MTI processing and compress the main signal of the velocity target. The measured data and simulation results are provided to confirm the effectiveness of the proposed algorithm.
