A noncontact measurement of the heart rate of a specific person using an X-band radar system with a four-element antenna array is presented. The system comprises a two-dimensional planar wide-beam antenna array with a four-channel network analyzer. The direction of arrival is est ...
We propose a fast method of ultrawideband (UWB) radar imaging that can be applied to a moving target, having in mind such application as concealed weapon detection. We demonstrate the performance of the proposed method using simulations and measurements with static and moving tar ...
Recently, the authors proposed a fast high-resolution imaging algorithm, called frequency-wavenumber (F-K) Kirchhoff migration. It was developed by combining three algorithms: F-K migration, Kirchhoff migration and inverse boundary scattering transform. The F-K Kirchhoff migratio ...
The authors have developed a target speed estimation method for an ultra-wideband radar imaging system. The method is able to generate a focused image even if the target is moving at an unknown speed during the measurement, where many other techniques produce blurred images. Our ...

We present frequency-domain Kirchhoff migration, which is a fast and high-resolution imaging algorithm for ultra-wideband radar. The algorithm is developed by combining three conventional methods: Kirchhoff migration, frequency-wavenumber (F-K) migration, and inverse boundary ...
