Linear Frequency Modulation (LFM) Time-Domain Millimeter-Wave Radar

77 – 81 GHz demonstrated

The Fourier-space scattered power mapping (FSPM) time domain (TD) reconstruction algorithm with a linearized integral scattering model offers much faster performance with LFM radars compared to QHM k-space algorithms or algorithms with Stohl's interpolation applied. The FSPM-TD reconstruction algorithm in its first stage for projection forming an inner product followed by its second stage of reconstruction for image deconvolution results in far fewer artifacts than other algorithm methods with spatial resolution close to theoretical limits.
