    A New Method of Testing Frequency-modulation Linearity of a LFMCW Radar

    • The linearity-correction technique is one of key techniques of a high resolution LFMCW radar. After linearitycorrection techniques and their corresponding linearity-testing methods are introduced, a new method of testing linearity of a LFMCW radar based on short-time Fourier transform and wavelet transform is also proposed. Furthermore, a modified method is presented. Simulation results show that it can efficiently test frequency-modulation linearity.
