My project is to use signals from multiple TR to understand what is happening with respect to motion. Ultrasound can provide distance and speed but I was interested in gaining more information from several transmissions and receipts. Including object recognition and direction of movement. I have worked a little with FFT. Can ultrasound differentiate an object by the reduction in amplitude because some of the wave was absorbed? And can ultrasound tell me the direction of speed by doppler shift. I play to have 3 TR, each 80 degree FOV and spaced on angles to cover an overlapping path.

Am a MetaTrader Expert I have a very wide experience in auto-trading bot with MetaTrader(MT4/MT5, MQL4/MQL5), TradingView(Pine Script), and QuantConnect(based on Python/C#) platforms. I am familiar with crypto-markets such as BitMex, Bittrex, Binance and so one. I have excellent knowledge including many strategies and indicators such as RSI, MACD, and EMA crossing indicators, BreakOut and Hidden Divergence indicators, etc. The project can be integrated into social media into e-mail and telegram for SIGNAL communication. And I am ready for professional back-testing and live trading. I can create an automated trading bot with PYTHON, PHP, or C#. Will be provided the professional front-end and strong back-end in case of the web-based system. And high quality, speed, period, and assistance. I will be very pleased to have the opportunity of doing your project

Hi I'm a Ph D computational scientist specialising in signal processing and acoustics. Recently I have been working on an acoustic simulation project involving ultrasonic wave propagation and i am quite familiar with the impulse response analysis and post-processing with respect to ultrasonic waves. The Python package I have been developing in this regard is a novel one which caters to the physics and engineering of indoors ultrasonic acoustics including Doppler effects . I will get your work done to your utmost satisfaction. You may consider me with confidence Regards Muthu

Hi, I have experience with signal processing and wave propagation from my imaging research. Both acoustic and electromagnetic (scalar approximation) waves obey the scalar Helmholtz equation, so the theory and signal processing should be very similar. If you'd like to discuss details further please feel free to contact me. Erik
