Field Documentation

◆ numBytesRxInfo

uint16_t numBytesRxInfo

Number of bytes in current struct.

Definition at line 1305 of file EMdgmFormat.h.

◆ numBeams

uint16_t numBeams

Number of beams in this datagram (Nrx).

Definition at line 1306 of file EMdgmFormat.h.

◆ numBytesPerBeamEntry

uint8_t numBytesPerBeamEntry

Bytes in EMdgmMWCrxBeamData struct, excluding sample amplitudes (which have varying lengths)

Definition at line 1307 of file EMdgmFormat.h.

◆ phaseFlag

uint8_t phaseFlag

0 = off
1 = logging of phase data is enabled.

Definition at line 1309 of file EMdgmFormat.h.

◆ TVGfunctionApplied

uint8_t TVGfunctionApplied

User selected log function constant (X) used in "X log R" TVG term for EMdgmMWCrxBeamData_def.sampleAmplitude05dB_p and EMdgmMRZ_sounding_def.reflectivity2_dB.
Default is 30. This gives a 30 log R TVG.

Definition at line 1310 of file EMdgmFormat.h.

◆ TVGoffset_dB

int8_t TVGoffset_dB

Time Varying Gain offset used (OFS), unit dB.

The user may select the BS offset to be applied (OFS = TVGoffset_dB). Default is 30 dB.
OFS is used to offset the 8 bit BS data in EMdgmMWCrxBeamData_def. sampleAmplitude05dB_p (0.5 dB resolution) to be able to record weak signals. With 30 dB offset the BS range will be -94 dB to + 34 dB, compared to +/- 64 dB. Also used by EMdgmMRZ_sounding_def.reflectivity2_dB.

Definition at line 1313 of file EMdgmFormat.h.

◆ sampleFreq_Hz

float sampleFreq_Hz

The sample rate is normally decimated to be approximately the same as the bandwidth of the transmitted pulse. Unit hertz.

Definition at line 1318 of file EMdgmFormat.h.

◆ soundVelocity_mPerSec

float soundVelocity_mPerSec

Sound speed at transducer, unit m/s.

Definition at line 1319 of file EMdgmFormat.h.
