    Design and implementation of a non-contact microwave level measument instrument
    (2010) Ward, Jonathan Michael; Inggs, Mike
    This dissertation describes the design and implementation of a microwave level measurement instrument for sensing the level of a substance inside a tank up to 10 m in height. A radar transceiver had to be designed to replace an acoustic sensor on an existing 4-20 mA loop powered ultrasonic instrument and had to be compatible with its on-board acoustic signal processing hardware. Specifications are developed for a pulsed radar architecture operating at 5.8 GHz with a bandwidth around 1 GHz and at a repetition frequency of 3.58 MHz.
