^SBDR_STRUCTURE = "SBDR.FMT" OBJECT = COLUMN NAME = ECHO_DATA DATA_TYPE = PC_REAL START_BYTE = 1273 ITEMS = 32768 ITEM_BYTES = 4 DESCRIPTION = "Array of 32,768 real samples of the RADAR echo return. Each real value is an antenna voltage estimate at a particular instant in time. These estimates are proportional to voltage but are expressed in data numbers and need to be converted to engineering units. The values may or may not have passed through a lossy BAQ compression/ decompression algorithm. The timing of the samples and other relevant RADAR instrument parameters are included in the engineering data segment of each LBDR record." END_OBJECT = COLUMN
