TLDR
The cell-averaging (CA) constant false-alarm rate threshold setting strategy is analyzed and the numerical results show that the CA strategy offers the desired false-Alarm probability.Abstract:
We analyze the impact of a uniform quantizer on the false-alarm probability of a total power radiometer. Different possibilities to set the detection threshold are discussed. The main emphasis is on methods that use the estimated noise level. In particular, we analyze the cell-averaging (CA) constant false-alarm rate threshold setting strategy. The numerical results show that the CA strategy offers the desired false-alarm probability.read more
