Members
int channel; Channel number being processed, zero indicates data is from a mono radar, a value of (1) indicates channel A, and value of (2) indicates channel B.
int offset; Offset between channels for a stereo radar.
int cp; Control program Identifier number.
int xcf; XCF flag.
int tfreq; Transmitted frequency.
int noise; Noise calculated from clear frequency search.
int nrang; Number of ranges.
int smsep; Sample separation (microseconds).
int nave; Number of pulse sequences transmitted.
int mplgs; Number of lags in ACF.
int mppul; Number of pulses in sequence.
int txpl; Transmit pulse length (microseconds).
int lagfr; Lag to first range (microseconds).
int mppul; Number of pulses in sequence.
int bmnum; Beam number.
int old; Set to indicate old data that used the 16 lag, 7 pulse code (pre-1993).
int old_elev; Set to use the old elevation angle routines.
int lag[LAG_SIZE][2]; Lag table.
int pulse[PULSE_SIZE]; Pulse table.
int pwr0[MAX_RANGE]; Lag-zero powers.
double interfer[3]; the x, y, z position of the interferometer array with respect to the main array. The values are given in meters. X is in the direction parallel to the main array, with +X being to the right looking along the boresite. Y is in the boresite direction, with +Y in front of the array. Z is the vertical displacement, with +Z being up.
double bmoff; Electronic beam offset angle.
double bmsep; Beam separation angle.
double phidiff; Sign of the phase shift of the interferometer array (+1 indicates the inteferometer is in front of the main array).
double tdiff; Time delay in microseconds of the signal from the interferometer array and the main array.
double vdir; Definition of velocity direction. (+1.0 is normal, -1.0 indicates that the I & Q inputs to the receiver are reversed).
Description

The struct FitPrm structure stores the parameters used by the fitacf algorithm.
