Phase Drift Compensation of Sub-THz Horn Antenna Pattern in Presence of Phase Center Offset …
When the phase center of an antenna and the rotation center are not perfectly aligned, phase drift occurs in the antenna pattern measurement. This issue becomes more severe at higher frequencies. This paper presents a method for estimating and compensating for phase center offset, even when the phase center offset is unknown. Additionally, …

Phase (waves)
Plot of one cycle of a sinusoidal function. The phase for each argument value, relative to the start of the cycle, is shown at the bottom, in degrees from 0 to 360 and in radians from 0 to 2π. In physics and mathematics, the phase (symbol φ or ϕ) of a wave or other periodic function of some real variable (such as time) is an angle-like quantity representing the …
Phase offset modulation
Phase offset modulation works by overlaying two instances of a periodic waveform on top of each other. (In software synthesis, the waveform is usually generated by using a lookup table .) The two instances of the waveform are kept slightly out of sync with each other, as one is further ahead or further behind in its cycle.
