Implementation of line detection via Hough transform constructs a target line segment with 2 signal-to-noise ratio and 34-pixel length in Gaussian-distributed noise background; after identifying the line equation, a fixed-length sliding window approach determines segment endpoints to precisely locate the line segment position. Algorithm includes Hough voting mechanism and peak detection for parameter space analysis.

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.
