Mutual Interference Mitigation of Millimeter-Wave Radar Based on Variational Mode Decomposition and Signal Reconstruction

Terahertz Imaging, Millimeter-wave Radar

The millimeter wave (MMW) band of frequencies extends from 30 GHz to 300 GHz, with some fuzziness on both ends of this spectrum. The terahertz (THz) band extends from about 200 GHz to about 30 THz, despite the fact that the lower frequencies in this range are not strictly 10 Hz or higher. These bands are also variously called submillimeter, far-infrared, and near-millimeter. In recent years, th...

Signal Processing of Automobile Millimeter Wave Radar Base on BP Neural Network

In this paper BP neural network is used for signal processing of automobile millimeter wave radar instead of FFT(Fast Fourier Transform). Simulation results show that BP neural network is superior to FFT. FFT has the drawback such as large computation and frequency spectrum leakage. The BP neural network has three layers(one input layer, one hidden layer, one output layer).The network is traine...

On the Coherent Phase Noise of Millimeter - Wave Doppler Radar

The phase noise is a very important index to wireless system, especially in millimeter-wave continuous wave radar systems. The phase noise of the signal, which is firstly leaked from transmitter and then mixed to intermediate frequency band by the local oscillator (Tx-IF), will worsen the sensitivity of superheterodyne radar system used for Doppler velocity detection. In this paper, the coheren...

Millimeter-Wave Circuit Design for Radar Transceivers

The 4 GHz Bandwidth Millimeter - Wave Radar

The landmark construction of the Advanced Research Projects Agency (ARPA)–Lincoln C-band Observables Radar (ALCOR) at Kwajalein Atoll in 1970 sparked significant interest in the ballistic missile defense (BMD) and satellite-identification communities [1]. ALCOR's 50 cm range resolution using 512 MHz bandwidth data confirmed the viability of valuable new BMD discrimination techniques and provide...
