Field Documentation

◆ numNoiseSamplesLeft

uint8_t HWA_AccelModeCFAR::numNoiseSamplesLeft

6 bit value: specify the number of samples used for noise averaging to the left of the cell under test. Note: The actual number of samples used for noise averaging in H/W is equal to the value of this field multiplied by 2 Sets the CFAR_AVG_LEFT (add note of factor of 2) bits of PARAM1_7

◆ numNoiseSamplesRight

uint8_t HWA_AccelModeCFAR::numNoiseSamplesRight

6 bit value: specify the number of samples used for noise averaging to the right of the cell under test. Note: The actual number of samples used for noise averaging in H/W is equal to the value of this field multiplied by 2 Sets the CFAR_AVG_RIGHT (add note of factor of 2) bits of PARAM1_7

◆ numGuardCells

uint8_t HWA_AccelModeCFAR::numGuardCells

3 bit value: specifies the number of guard cells to ignore on either side of the cell under test Sets the CFAR_GUARD_INT bits of PARAM1_6

◆ nAvgDivFactor

uint8_t HWA_AccelModeCFAR::nAvgDivFactor

4 bit value: specifies the division factor by which the noise sum calculated from the left and right noise windows are divided by in order to get the final surrounding noise average value. The division factor is equal to 2^nAvgDivFactor Valid values: 0-8 Sets the CFAR_NOISEDIV (add note) bits of PARAM1_6

◆ nAvgMode

uint8_t HWA_AccelModeCFAR::nAvgMode

2 bit value: See HWA_NOISE_AVG_MODE_CFAR macros for correct values. configures the noise averaging mode in the CFAR detector Sets the CFAR_CA_MODE bits of PARAM1_7

◆ operMode

uint8_t HWA_AccelModeCFAR::operMode

See HWA_CFAR_OPER_MODE macros for correct values. Sets the CFAR_LOG_MODE, CFAR_INP_MODE, CFAR_ABS_MODE bits of PARAM1_0

◆ outputMode

uint8_t HWA_AccelModeCFAR::outputMode

2 bit value: See HWA_CFAR_OUTPUT_MODE macros for correct values. select the output mode of the CFAR engine Sets the CFAR_OUT_MODE bits of PARAM1_7

◆ peakGroupEn

uint8_t HWA_AccelModeCFAR::peakGroupEn

1 bit value: See HWA_FEATURE_BIT macros for correct values. specifies whether peak grouping should be enabled HWA_FEATURE_BIT_DISABLE - peak grouping is disabled, which means that a peak is declared as detected as long as the cell under test exceeds the threshold HWA_FEATURE_BIT_ENABLE - peak is declared as detected only if it the cell under test exceeds the threshold, as well as, if the cell under test exceeds the two neighboring cells to its immediate left and right Sets the CFAR_GROUPING_EN bits of PARAM1_0

◆ cyclicModeEn

uint8_t HWA_AccelModeCFAR::cyclicModeEn

1 bit value: See HWA_FEATURE_BIT macros for correct values. specifies whether the CFAR-CA detector needs to work in cyclic mode or in non-cyclic mode HWA_FEATURE_BIT_DISABLE=non-cyclic mode HWA_FEATURE_BIT_ENABLE=cyclic mode Sets the CFAR_CYCLIC bits of PARAM1_0
