WebFirst, the difference between the coherent and noncoherent results decreases with increasing frequency for the same m for the m = 3 and 4 cases. The results for the m = 2 case show that the improvement factor is very similar at lower frequencies but performance diverges at higher frequencies. WebIntegration across antenna can be coherent or non-coherent. Non-coherent integration losses 1~3 dB gain depending on the number of antenna. Coherent integration across the antennas can be implemented by FFT. Detection can be done after coherent or non-coherent integration.

It is commonly used to estimate the power transfer between input and output of a linear system. somewhere over the rainbow harp

"WebCoherent scatter radar provides a unique perspective of Joule heating by accessing both very small scales, but also providing spatial observations over mesoscales. However, investigations specifically focused on Joule heating from coherent radar observations are relatively limited compared to incoherent scatter radar. " - Coherent vs non coherent radar
