Description: 原理图中并接在超声波接收头两端的瓷片电容不用的话可以增强信号，但是抗干扰性不强。我的做法是牺牲抗干扰性，提高距离，呵呵，没办法只能这样了。另外还有要说明的是发送与接收探头的距离是8个cm！！这样才能保证测量距离，我做好的测距距离是接近6米。发送与接收探头的距离可能还可以小一点，但不能小于4cm（网上说的），我做过间距为2cm的时候测距距离为3米左右-Schematic diagram of the ultrasonic receiver and then the first ceramic capacitors at both ends so no need to enhance the signal, but do not have a strong anti-interference. My approach is the expense of anti-jamming and increase the distance Oh, no way can only be the case. Another note is sent to and received from the probe was 8 cm! ! Way to ensure the distance measurement, I do a good job close to the range distance is 6 meters. Send and receive the distance between the probe may also be smaller, but not less than 4cm (online said), I had the time spacing ranging from 2cm to about 3 meters

Description: Multiple-input multiple-output (MIMO) radar has been receiving increasing attention
in recent years from researchers, practitioners, and funding agencies. MIMO radar is
characterized by using multiple antennas to simultaneously transmit diverse (possibly
linearly independent) waveforms and by utilizing multiple antennas to receive the
reflected signals. Like MIMO communications, MIMO radar offers a new paradigm
for signal processing research. MIMO radar possesses significant potentials for
fading mitigation, resolution enhancement, and interference and jamming suppression.
Fully exploiting these potentials can result in significantly improved target
detection, parameter estimation, as well as target tracking and recognition
performance.

Description: 數位訊號處理（英語：DSP, Digital Signal Process）是將訊號以數位方式表示並處理的理論和技術。數位訊號處理與模擬訊號處理是訊號處理的子集。
數位訊號處理的目的是對真實世界的連續模擬訊號進行測量或濾波。因此在進行數位訊號處理之前需要將訊號從模擬域轉換到數位域，這通常通過模數轉換器實現。而數位訊號處理的輸出經常也要變換到模擬域，這是通過數模轉換器實現的。
數位訊號處理的算法需要利用計算機或專用處理設備如數位訊號處理器和專用積體電路等。數位訊號處理技術及設備具有靈活、精確、抗干擾強、設備尺寸小、造價低、速度快等突出優點，這些都是模擬訊號處理技術與設備所無法比擬的。-Digital signal processing (English: DSP, Digital Signal Process) is the signal to a digital representation of the theory and techniques and processed. Digital signal processing and analog signal processing is a subset of the signal processing. The purpose digital signal processing is the real world of continuous analog signal measurement or filtering. Therefore, prior to digital signal processing you need to convert signals the analog domain to the digital domain, which is usually realized by ADC. The output of digital signal processing often have converted to the analog domain, which is achieved through digital to analog converter. Digital signal processing algorithms need to use a computer or a dedicated processing equipment such as digital signal processors and application specific integrated circuit. Digital signal processing technology and equipment with flexible, precise, strong anti-jamming equipment, small size, low cost, speed and other advantages, which are analog signal pro
