Probability of detection in radar

A typical radar system will operate with a detection probability of 0.9 and a probability of false alarm of 10-6.

What is the probability of detection?

The concept of Probability of Detection (POD) is used in various industry sectors to establish the capability of an inspection to detect flaws. This is generally expressed as a POD curve, which relates the likelihood of detection to a characteristic parameter of the flaw, usually its size.

How probability of detection affects probability of false alarm in radar?

For all faults of the system, it is assumed that the probability of miss detection is fixed to 0.02 and the probability of false alarms is fixed to 0.05.

Radar Basics

The detection process separates the required target from the noise and clutter. Detectors are normally designed to carry out this process with a constant false alarm rate (CFAR). The diagram shows the location of the detector in the chain of signal processing.

What should be the required probability of detection and probability of false alarm for a successful design of the lidar?

The detection probability is P_d = 99% and the false-alarm probability is P_fa = 1%.
