Clicking on the radar image starts and stops the animation.With a desktop browser, when hovering over the radar image, you can use the mousewheel to zoom and then pan by clicking and dragging.A maximum of 500 frames are shown for a given period....
A nanosecond pulse doppler radar adapted to hypersonic ballistic range studies is disclosed. The doppler signal is processed to give a continuous record of amplitude and phase using conventional narrow band electronics. The nanosecond pulses transmitted by the radar are obtained through TWT amplification...
A Doppler radar sensor platform suitable for measurements of vibration and velocity of any objects is described here. The platform consists of several multipurpose transceivers operating at two different millimeter(mm)-wave frequency bands. Silicon-Germanium BiCMOS technology enables the implementation of ...

Download the latest Raymarine Quantum 2 Doppler radar software. Doppler target tracking intelligently highlights inbound radar contacts in red, and outbounds in green. Plus, Quantum 2 offers all of the same great benefits as the original Quantum radar.
Let us now make some approximations to gain physical insights. First, we consider small velocities compared to the speed of light v/c ≪ 1, for which the frequency Doppler shift is approximately 2ωcv/c. Let us now introduce the spectral amplitudes’ Fourier transform g(t) = ∫...
A Doppler radar simulator is provided for generating signals for testing Doppler radar navigational systems. The Doppler simulator of the invention utilizes digital techniques in order to perform with
The sky is scanned with transmitted radar pulse beam of electromagnetic radiation from a high gain antenna with a narrow viewing angle, and by monitoring the echoes with a low gain receiving antenna t
