Summary
• Both target properties and radar design features affect the ability to detect signals in noise
• Fluctuating targets vs. non-fluctuating targets
• Allowable false alarm rate and integration scheme (if any)
• Integration of multiple pulses improves target detection
• Coherent integration is best when phase information is available
• Noncoherent integration and frequency diversity can improve detection performance, but usually not as efficient
• An adaptive detection threshold scheme is needed in real nvironments
• Many different CFAR (Constant False Alarm Rate) algorithms exist to solve various problems
• All CFARs algorithms introduce some loss and additional processing
