Abstract:
    Methods and apparatus for sensing pressure in a hostile environment are described. In one example embodiment, a microwave radar based sensor (40) is provided. The sensor is coupled to a signal conditioning unit (50). The signal conditioning unit includes at least one of a processor configured to determine a sensor value and a memory having pre-stored values therein, the pre-stored values representing possible sensor values. Each pre-stored value is assigned a respective pressure. The method includes operating the signal conditioning unit to sample a signal generated by the sensor, operating the signal conditioning unit to correlate a characteristic of the sampled signal to a pre-stored value having an assigned pressure, and operating the signal conditioning unit to generate a signal representative of the assigned pressure of the pre-stored value that is correlated to the sampled signal.
