Sensible defaults are used if a particular environment variable is not set. The following table lists the settable environment variables and their effects. File name must be less than 255 characters. Because of limitations in the ifam structure, a maximum of 120 ACFs may be constructed. This variable controls how lag product matrices are summed to produce ACFs for the case of single long pulse modes.
NONE Produce no ACF values at all - i.e. ACFs are all zero.
Range resolution is the same for all lags. Range resolution is the same for all lags. The size of the trapezoid at zero lag is set at the number of diagonals in the lpm. This is equivalent to windowing in range, then summing together all appropriate lag products at each delay. The range window size is set at the number of diagonals in the lpm.
