    [1] The operator hears the echoes from any reflection. Therefore, it performs transmission/listening continuously, which covers the space 360 °. The primary radar functions, therefore, results in detection and measurements of position if there is the presence of a target by the recognition of the useful signal. A primary radar measurement include:

    This is possible since the reflective characteristics of humans are generally more diverse than those of the materials typically used in construction. However, since humans reflect far less radar energy than metal does, these systems require sophisticated technology to isolate human targets and moreover to process any sort of detailed image.

    The klystron tube transmitter operates in the S-band between 2.5 and 2.9 GHz in circular polarization with a peak power of 1.3 MW and a pulse duration of 1 μs and pulse repetition frequency between 325 and 1200 pps. It can be switched to a second reserve frequency if interference is encountered on the primary frequency.
