SNR <strong>of</strong> Coherent vs Incoherent Averaging<br />

Two methods <strong>of</strong> signal detection with different level <strong>of</strong> the input noise<br />

(zero-mean Gaussian noise with std deviation σ)<br />

Coherent Averaging <strong>of</strong> 100 chirps Incoherent Averaging <strong>of</strong> 100 chirps<br />

Coherent Averaging <strong>of</strong> 100 chirps<br />

σ = 100<br />

SNR = -23 dB<br />

σ = 150<br />

SNR = -25 dB<br />

Incoherent Averaging <strong>of</strong> 100 chirps
