Hi,
In the \mmwave_mcuplus_sdk_04_02_00_01\ti\alg\gtrack\src\gtrack_utilities_3d.c file, the function gtrack_calcMeasurementSpread is defined as belows:
void gtrack_calcMeasurementSpread(float range, GTRACK_gateLimits *gate_limits, GTRACK_measurement_vector *estSpread)
{
if(gate_limits->depth <= FLT_MIN)
estSpread->range = GTRACK_NOMINAL_RANGE_SPREAD;
else
estSpread->range = gate_limits->depth;
if(gate_limits->width <= FLT_MIN)
estSpread->azimuth = GTRACK_NOMINAL_ANGULAR_SPREAD;
else
estSpread->azimuth = 2*atanf((gate_limits->width/2)/range);
if(gate_limits->height <= FLT_MIN)
estSpread->elev = GTRACK_NOMINAL_ANGULAR_SPREAD;
else
estSpread->elev = 2*atanf((gate_limits->width/2)/range);
/* Initial value of doppler spread */
estSpread->doppler = GTRACK_NOMINAL_DOPPLER_SPREAD;
}
In the above code: estSpread->elev = 2*atanf((gate_limits->width/2)/range); is there anything wrong? Should the correct description be estSpread->elev = 2*atanf((gate_limits->height/2)/range)?I dont know my understanding is right or not.If wrong,why should the value estSpread->elev be like this?
