At present, the sensitivity of the detector-amplifier, in terms of the axion mass it can detect, is ranging from 5 to 13 [mu]eV and centered at around 11 [mu]eV (without making any changes in the cavity), whereas its sensitivity in terms of the weakest signal it can measure is approximately -100 dBm ([+ or -] 10 dBm) at the frequency of 2 GHz (corresponding to an axion mass of around 13 [mu]eV) with a significant SNR (equal to or greater than 2); however, the latter would improve greatly with the inclusion of a SQUID device in the detection stage, with sensitivity of the instrument reaching the levels of SQUID's Minimum Detectable Signal.
In this paper, we propose an active-margin transmission power control (AM-TPC) algorithm using effective minimum detectable signal (EMDS) to achieve short stabilization time as well as reliability in mobile environments.
The MDS represents the minimum detectable signal and SNRdemod describes a SNR required from a digital baseband-demodulator.
Reducing this noise would result in a reduction of the minimum detectable signal and, therefore, an improvement in the overall range of the radar.
Due to the SNR requirement of 12 dB, the minimum detectable signal will need to be -72 dBm, (-60 dBm - 12 dB).
