Assessment of Measurement Distortions in GNSS Antenna Array Space-Time Processing

Table 1

Comparison of few features offered by beamformers.

Parameter description	Beamforming method
	Blind eigenvector	MPDR	E-MPDR	C-DL
Use of steering vector	No	Yes	Yes	Yes
Computational complexity	Less	Moderate	High	High
Space (S) or space-time (ST)	ST	S	ST	ST
Distortions	Maximum	No distortion	Moderate	Minimum
Number of filter weight sets	Single	Multiple	Multiple	Multiple

Separate steering vector is used for each satellite.
