  1. Firstly, the theory and the architecture of hardware system are described, secondly, the steps of the signal processing are discussed in detail. based on the experiments and the characteristics of the signal, we pre - process the signals with band - pass filter, proportional amplifier and coherent demodulator. after sampling and analysis doppler information, we display the final results distinctly to alarm in time

    然後,結合系統中各主要部分的任務,詳細介紹了信號處理的各個步驟:通過實驗比較,並結合接收信號的特點,選用帶通濾波器、比例放大器、相干檢波等技術對信號進行預處理;然後對獲得的多卜勒信息進行采樣和頻譜分析;最後,用比較直觀的形式顯示數據結果,以及時準確地告警。
