In the radar receiver, the returning echoes are typically received by the antenna, amplified, down-converted to an intermediate frequency, and then passed through detector circuitry that extracts the envelope of the signal, known as the video signal. This video signal is proportional to the power of the received echo. It comprises the desired echo signal as well as the unwanted signals from internal receiver noise and external clutter and interference. The term video refers to the res… WebbThe radar must detect, with greater than or equal to 80% probability at a defined range, a one square meter radar cross section. This relatively bad result is a compromise between the probability of detection and the false alarm rate. This means: One of five targets won't be detected by radar with analog signal processing.

Fluctuation Loss - Radartutorial

In statistics, when performing multiple comparisons, a false positive ratio (also known as fall-out or false alarm ratio) is the probability of falsely rejecting the null hypothesis for a particular test. The false positive rate is calculated as the ratio between the number of negative events wrongly categorized as … Visa mer The false positive rate is $${\displaystyle FPR={\frac {\mathrm {FP} }{\mathrm {FP} +\mathrm {TN} }}}$$ where $${\displaystyle \mathrm {FP} }$$ is the number of false positives, The level of … Visa mer While the false positive rate is mathematically equal to the type I error rate, it is viewed as a separate term for the following reasons: Visa mer • False positives and false negatives • False coverage rate • False discovery rate • Sensitivity and specificity Visa mer WebbSwerling shows in his publication, that an additional fluctuation loss depends more on the probability of detection and less on the probability of false alarms PN. Given values of the theoretically maximum range of a tracking radar set are based on the Swerling II and IV Target Model often. bouncy mask
