    looks pretty much like a FET, RF amplifier followed by a diode detector and an audio amplifier :)

    have you got any more background on the cct ? where did it come from ?

    Its a question from an unknown book. In the question it is regarded as EM survey unit

    Sorry I should have posted this before.

    It looks as if the circuit will not work without a DC path for the diode. Add a resistor from the junction of C and the diode to ground. It would also help if there was power to the amplifier!
