Probability of Detection Solution

STEP 0: Pre-Calculation Summary

Formula Used

Detection Probability of Radar = 1-(1-Cumulative Probability of Detection)^(1/N Scans)
p_detect = 1-(1-p_c)^(1/n)
This formula uses 3 Variables

Variables Used

Detection Probability of Radar - Detection Probability of Radar is defined as the probability of finding or surveilling the object inside the radar.
Cumulative Probability of Detection - Cumulative probability of detection is defined as the ratio of detected aims to the number of all possible blips on the radar screen, i.e. all possible targets in a given direction.
N Scans - N scans refers to the total number of scans run during radar detection.

STEP 1: Convert Input(s) to Base Unit

How do you find the probability of a false alarm?

False alarm is “an erroneous radar target detection decision caused by noise or other interfering signals exceeding the detection threshold”. In general, it is calculated by ratio of false targets per pulse repetition time to number of range cells.

How to Calculate Probability of Detection?

Probability of Detection calculator uses Detection Probability of Radar = 1-(1-Cumulative Probability of Detection)^(1/N Scans) to calculate the Detection Probability of Radar, Probability of Detection refers to the likelihood or probability that a radar system or antenna will correctly detect the presence of a target or signal of interest. It is a critical performance metric used to assess the effectiveness and reliability of a radar system or an antenna in detecting and tracking targets. Detection Probability of Radar is denoted by p_detect symbol.

How to calculate Probability of Detection using this online calculator? To use this online calculator for Probability of Detection, enter Cumulative Probability of Detection (p_c) & N Scans (n) and hit the calculate button. Here is how the Probability of Detection calculation can be explained with given input values -> 0.249667 = 1-(1-0.4375)^(1/2).

FAQ

What is Probability of Detection?

Probability of Detection refers to the likelihood or probability that a radar system or antenna will correctly detect the presence of a target or signal of interest. It is a critical performance metric used to assess the effectiveness and reliability of a radar system or an antenna in detecting and tracking targets and is represented as p_detect = 1-(1-p_c)^(1/n) or Detection Probability of Radar = 1-(1-Cumulative Probability of Detection)^(1/N Scans). Cumulative probability of detection is defined as the ratio of detected aims to the number of all possible blips on the radar screen, i.e. all possible targets in a given direction & N scans refers to the total number of scans run during radar detection.

How to calculate Probability of Detection?

Probability of Detection refers to the likelihood or probability that a radar system or antenna will correctly detect the presence of a target or signal of interest. It is a critical performance metric used to assess the effectiveness and reliability of a radar system or an antenna in detecting and tracking targets is calculated using Detection Probability of Radar = 1-(1-Cumulative Probability of Detection)^(1/N Scans). To calculate Probability of Detection, you need Cumulative Probability of Detection (p_c) & N Scans (n). With our tool, you need to enter the respective value for Cumulative Probability of Detection & N Scans and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
