With a radio-telescope array, which mechanism limits angular resolution improvement when increasing the signal processing capability?

💡 Explanation

Angular resolution in radio astronomy will ultimately be bounded by atmospheric effects. Tropospheric signal phase decorrelation increases with baseline length because variations introduce independent phase shifts, therefore decorrelation prevents further improvements, rather than bandwidth affecting angular resolution.
