To solve the parameter estimation problem of accelerating target in LFMCW(linear frequency-modulated continuous wave)radar while MTRC(migration through range cell)occurs,a velocity-acceleration template matching method based on partial compensation is presented.

To solve the parameter estimation problem of accelerating target in LFMCW(linear frequency-modulated continuous wave) radar while MTRC(migration through range cell) occurs,a direct phase difference method is proposed.

In the wideband conical scan radar,the sensitivity to the radial velocity between the radar and the target induces the range migration through resolution cells among the high range-resolution profiles.

According to the problem of target range migration through resolution cells in a long-term integration,a long-term coherent integration method is proposed to maintain the detection sensitivity of the radar.

The simulation results show that using big element space can suppress the grating lobe well.
