Moving target detection for FMCW radar

Proceedings of 2011 IEEE CIE International Conference on Radar, 2011
From the spectrum characters of triangular FMCW radar and the comparability of the frequency envelope of fixed clutters, an algorithm on restraining fixed clutters and MTD is proposed by calculating the spectrum energy centre. And distance and speed error are corrected by partner algorithm in frequency domain.

GaAs monolithic circuit for FMCW radars

IEEE 1988 Microwave and Millimeter-Wave Monolithic Circuits Symposium. Digest of Papers., 2003
A brief description is given of a monolithic GaAs chip that incorporates a varactor-tuned voltage-controlled oscillator (VCO), buffer amplifier and double balanced mixer with active phase splitters for an FM continuous-wave (CW) radar transmit-receiver.

Steady-state tracking with FMCW radars

2018 IEEE Aerospace Conference, 2018
Kalman filters are typically used for tracking, but they are not convenient for predicting performance and filter design. However, Kalman filters can be approximated with steady-state equivalents like the α-β filter for the nearly constant velocity (NCV) Kalman filter processing measurements of position.

Digital beamforming calibration for FMCW radar

IEEE Transactions on Aerospace and Electronic Systems, 1989
Three sources of beamforming deterioration are identified for an FMCW radar. These all relate to time-of-arrival and cable delays. There are small range-dependent phase errors at the receiver outputs. The delays cause frequency shifts, which produce phase errors at the discrete Fourier transform (DFT) outputs after ranging. These frequency shifts cause

Advances in millimetre wave FMCW radar

2008 Microwaves, Radar and Remote Sensing Symposium, 2008
This paper addresses some of the recent advances in frequency modulated continuous wave (FMCW) radar at millimetre wave frequencies. It describes a coherent radar architecture incorporating direct digital synthesis (DDS) and, in particular, the choice of stable local oscillator (STALO).

Phase-Coded FMCW for Automotive Radars

2023
Autonomous driving is a new emerging technology that will enhance traffic safety. Automotive radars are essential to attaining autonomous driving since they can function in adverse weather conditions and are used for detection, tracking, and classification in traffic settings.

FMCW radar altımeter test board

2020
Bu tezde darbe modülasyonlu frekans modülasyonlu sürekli dalga radarı analiz edilmiş ve gönderilen sinyale laboratuar ortamında zaman gecikmesi eklenmesi uygulanmıştır. Radardan gönderilen sinyalde radar ile hedef arasındaki yolculuğundan kaynaklanan bir zaman gecikmesi vardır.
