This avoids the problem of a sensitive receiver trying to operate simultaneously with a high power transmitter. Figure 2. A representation of basic radar operation. Range bins The pulse width or duration is an important factor. The radars operate by “binning” the receive signals. The receive ...
Thus, the radar system of the present invention offers improved fade elimination, interference insensitivity, and range ambiguity.Howard J. KrizekGordon M. JohnsenH. J. Krizek and G. M. Johnsen, "Frequency agile radar," U.S. Patent 5 347 283 A, Sep. 13, 1994....
Radar systems provide an important remote sensing capability, and are crucial to the layered sensing vision; a concept of operation that aims to apply the right number of the right types of sensors, in the right places, at the right times for superior battle space situational awareness. The la...
any of the electromagnetic wave frequencies that lie in a range extending from below 3 kilohertz to about 300 gigahertz and that include the frequencies used for communications signals (as for radio and television broadcasting and cell-phone transmissions) or radar signals—often hyphenated when used...
