THE EFFECTS OF POWER UNDULATION IN FREQUENCY SWEEP ON THE RANGE PRECISION AND RANGE RESOLUTION OF LFMCW RADAR
|
Abstract:
The transmitting signal of Linear Frequency Modulation Continuous Wave (LFMCW) radar has two nonideal parameters: sweep nonlinearity and power undulation. They make the practical range precision and range resolution of LFMCW radar decrease. This paper analyses the effects of the power undulation on the range precision and range resolution according to the echo power spectrum of LFMCW radar, and gives theoretical bases for choosing its oscillator.
