target signal

The radar energy returned to a radar by a target. Also called an echo signal or a video signal. The amount of this energy is called received power. The size of the echo on the PPI (plan position indicator) is a direct function of the received power. See echo.

From Doppler radar spectrum basics and LPI radar models to extended target signal processing, electronic security and military personnel will find this an in-depth and specific engineering guide packed with graphs, charts, and specific calculations.
The BSS acts as a set of beamformers, which separates the target signal from the background noise by using the L observations.
This assumption is used to enhance a noise-corrupted target signal by subtracting an estimated average noise spectrum from the noisy signal spectrum, restoring the spectrum of the target signal observed in additive noise [33], and this is called the spectral subtraction technique.
The short separation measurement is used as the reference signal, and the long separation measurement is treated as the target signal [10].
x(t) is set as target signal, and then the signal added to white noise is x(t) + [[epsilon].sub.0][[omega].sup.i](n).
The focal ratio is the unifying factor, and it works across all optics as a concrete metric of how long you'll need to expose for a target signal per pixel for a given subject.
Among them, the object of ES is to immediately detect target signal in a war, and ES's activities include detecting and monitoring radiated electromagnetic wave energy, producing information through direction finding and identification process, and providing the information of target for EA.
