Radar detectionSignal resolutionReceiversClutterJammingThe paper discusses the factors which affect the bandwidth which should be chosen for a radar's transmissions. It highlights the importance of clutter reduction and resistance to interception, as well as the limits due to target splitting, the ...
Then there are the so-called “short waves,” i.e., radar waves, millimeter waves, and so on. There are no actual boundaries between one range of wavelengths and another, because nature did not present us with sharp edges. The number associated with a given name for the waves are only...
L 1940s, radars had become small enough to be im- sists of a radar sensor mounted on an airborne (or To form a two-dimensional image, the echoes plemented on airplanes, expanding the application spaceborne) platform that, in this simplifed exam- received from the ground are sorted by ...
The following sections use the ambiguity function to explore the range-Doppler relationship for several popular waveforms. To establish a comparison baseline, assume that the design specification of a radar system requires a maximum unambiguous range of 15 km and a range resolution of 150 m. Get ...
In the PS-Poll frame, the Duration/ID field is an association ID rather than a value used by the virtual carrier-sensing function. When mobile stations associate with an access point, the access point assigns a value called the Association ID (AID) from the range 1-2,007. The AID is ...

a maximum extinction rate of 1.6 (1.2–1.9) × 10−4/species/year, roughly equivalent to ~160 (120–190) extinctions per million species years (E/MSY). This is approximately 80 (60–95) times the background extinction rate, here set to 2 E/MSY following previous assessments18(a ...
The JUBA station correlograms are evaluated as a function of time, shifting sample by sample the template event window through continuous waveforms. We use 6 samples tolerance in detecting maximum cross-correlation amplitude for each channel. To declare candidate detections, we initially set the thres...

Accuracy is obtained by careful measurement of the baseline length and orientation and the location of the platform relative to the reference coordinate system. As radar wavelengths in the centimeter to meter range furnish good signal returns from rough surfaces such as bare ground, rough water, ...
