In this paper, a range calibration and modulation sweep linearity verification method of a helicopter-borne FM-CW (Frequency-Modulated Continuous Waveform) profiling radar are presented. The radar is designed to collect backscatter signal waveforms to build target stand profiles. Various forest elements e.g. tree height; density; species, etc. can be evaluated through this profiling radar. This paper investigates the relation between target range and the received corresponding backscatter signal frequency and verifies the linearity of modulated RF (radio frequency) signal. The calibration result can be achieved based on a ground calibration test with restricted distance rather than the full measurement range. And the calibrated output can be directly adopted for airborne forestry inventory. The field test proves that the proposed calibration method is applicable for FMCW radar calibration using a centimeter level accurate fly trajectory with the help of Global Navigation Satellite System (GNSS) and IMU (Inertial Measurement Units) and a DEM (Digital Terrain Model) of the test field.
