Abstract:

A statistical analysis on the output signals of an acousto-optic spectrum analyzer AOSA is performed for the case when the input signal is a continuous-wave CW. To this end, a statistical model of these output signals is presented as a basis for the different analyses along with some numerical algorithms to calculate the deterministic components on a digital computer. Using this model, the optimum test for the detection of a known frequency is derived and its performance is analyzed. To deal with the unknown frequency situation, a scheme which was easily implemented with a finite impulse response FIR filter is presented and its performance degradation as compared to the case of a known frequency is analyzed.
