Coding schemes for improving MST radar performance, part 7.1A [PDF]
The performance of an mesosphere-stratosphere-troposphere (MST) radar can be characterized by its system sensitivity and its range resolution. The former enables Doppler velocities to be determined even in the presence of very weak structures; the latter

Maximum Available Accuracy of FM-CW Radars
Radioengineering, 2009 This article deals with the principles and above all with the maximum available measuring accuracy analyse of FM-CW (Frequency Modulated Continuous Wave) radars, which are usually employed for distance and velocity measurements of moving objects in road traffic, as well as air traffic and in other applications. These radars often form an important part

Radar investigation of asteroids [PDF]
The dual polarization CW radar system which permits simultaneous reception in the same rotational sense of circular polarization as transmitted (i.e., the "SC" sense) and in the opposite ("OC") sense, was used to observe five previously unobserved ...

Advanced polarimetric subsurface FM-CW radar
Advanced polarimetric subsurface FM-CW radarThe subsurface radar suffers from two typical problems, i.e., strong clutter from surface and severe wave attenuation in the underground. This paper presents a unique countermeasure to these problems using a polarimetric FM-CW radar and an equivalent sensitivity time control (STC) technique.

A comparison of laser-based ranging systems for AR/C [PDF]
The three most common types of laser target ranging (time-of-flight, tone modulated, and FM-CW) are discussed in terms of principle of operation.

IF filter optimization for CW-FM radar.
, 1975 A continuous -wave frequency-modulated radar receiver and the IF filter are described. IF filter responses are investigated from the output of the narrow bandpass filter for various target ranges. The effects of the IF signal pulse width and the duty cycle on the IF filter output including the change of the sidelobe levels out of the filter are ...
