In signal processing, the coherence is a statistic that can be used to examine the relation between two signals or data sets. It is commonly used to estimate the power transfer between input and output of a linear system. If the signals are ergodic, and the system function is linear, it can be used to estimate the causality between the input and output. WebTherefore, the complex envelopes of the DP signal and the multipath signal will be misalignment, leading to the failure of the joint steering vector class method for signal detection. 3. The Proposed Incoherent Integration Detection Method 3.1. The Proposed Method. The CFAR is a common signal detection method.
