CCS/AWR1443BOOST: Minimum Range of AWR1443

Part Number:AWR1443BOOST

Tool/software: Code Composer Studio

Hi,

I'm trying out the Power Optimization/ Level sensing demo on the AWR1443 but i realised the range measurements are quite inaccurate at shorter distance from the sensor. Im using a certain configuration and wondered if changing any of these parameters would result in better range measurements at around 10cm distance away from the sensor.

#ifdef  DEMO_CONFIG1
//Description: Short range with good resolution. Low processing.
//max range: 4.5m
//range resolution: 3cm
#define DEMOCFG_SAMPLE_RATE            4500        /* 4.5Msps */
#define DEMOCFG_FREQ_SLOPE             930         /* x 48.28kHz/us = 45Mhz/us */
#define DEMOCFG_IDLE_TIME              1500        /* 15us */
#define DEMOCFG_ADC_START_TIME         400         /* 4us */
#define DEMOCFG_RAMP_END_TIME          8900        /* 89us */
#define DEMOCFG_RANGE_RES              0.0294
#define DEMOCFG_NUM_ADC_SAMPLES        376
#define DEMOCFG_FFT_SIZE               512
#endif

Thanks
