Cumulative Probability Of Detection Equation:
| From: | To: |
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.
The calculator uses the cumulative probability equation:
Where:
Explanation: The equation calculates the probability that a target will be detected at least once over multiple radar scans, accounting for the cumulative effect of repeated detection attempts.
Details: Accurate cumulative probability calculation is crucial for radar system performance evaluation, mission planning, and determining the effectiveness of surveillance operations over multiple scans.
Tips: Enter detection probability (0-1) and number of scans. All values must be valid (detection probability between 0-1, number of scans ≥1).
Q1: What is Detection Probability Of Radar?
A: Detection Probability of Radar is defined as the probability of finding or surveilling the object inside the radar during a single scan.
Q2: What are N Scans?
A: N scans refers to the total number of scans run during radar detection operations.
Q3: Why does cumulative probability increase with more scans?
A: With each additional scan, there's another opportunity to detect the target, making it more likely that the target will be detected at least once over multiple scans.
Q4: What is the maximum value of cumulative probability?
A: The maximum cumulative probability is 1 (or 100%), meaning the target is certain to be detected over enough scans.
Q5: How does detection probability affect cumulative results?
A: Higher single-scan detection probabilities lead to faster convergence to high cumulative probabilities with fewer scans required.
