Compact mmWave FMCW radar: Implementation and performance analysis

FMCW Radar Performance for Atmospheric Measurements

Frequency-modulated continuous-wave radars (FMCW) have been used in the investigation of the atmosphere since the late 1960’s. FMCW radars provide tremendous sensitivity and spatial resolution compared to their pulsed counterparts and are therefore attractive for clear-air remote-sensing applications. However, these systems have some disadvantages and performance limitations that have prevented...

Analysis of mmWave Performance

Fmcw Based Mimo Imaging Radar

There are a number of potential applications for low cost short range phased array radar sensors: ship bumpers, large vehicle sensors and level crossing obstacle detection for example. Phased arrays have the benefit of reduced size and the elimination of moving parts compared with more traditional rotating antenna systems. Another potential benefit is that the image update rate can be orders of...

Detection Performance Improvement of FMCW Radar Using Frequency Shift

Frequency modulated continuous wave (FMCW) radars have been widely used for measuring target range and speed. In this paper, we present a mathematical model that quantifies the system-level performance of FMCW radar systems. In FMCW radar, the target range is measured through measuring the beat frequency between the transmitted and received signal, usually by using Fast Fourier Transform (FFT)....

Design and Analysis of 4-GHz SOP FMCW HMIC Radar

The demand for higher performance systems that are smaller and have the potential to be more cost effective has lead hardware designers to adopt integration of many components and modules in a package (SOP) or on a chip (SOC). A compact SOP (single-substrate) L-band FMCW HMIC radar module for high-resolution sensor application has been demonstrated. For use with a single transmitreceive antenna...
