In detection and estimation theory, simulations demonstrate the relationship between detection probability (Pd) and false alarm probability (Pfa), where Pfa=1-Q(z) and Pd=1-Q(z-d). This involves plotting Pfa versus Pd for different values of d, which can be implemented using Gaussian Q-function calculations and visualization techniques in programming environments like MATLAB or Python.

Simulate detection performance across varying SNR levels by generating different target model data under false alarm probability constraints. The radar system employs square law detection followed by non-coherent integration of 10 pulses. Implementation includes generating Swerling 0-IV type target signals with additive white Gaussian noise. Monte Carlo simulations (≥10^5 iterations) are performed for SNR ranging from -10dB to 10dB in 1dB steps, with false alarm probability fixed at 10^-6. Detection probability (Pd) vs SNR curves are plotted to analyze system performance.
