Continuous-wave radar (CW radar) is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects. [1] Individual objects can be detected using the Doppler effect , which causes the received signal to have a different frequency from the transmitted signal ...
Its maximum range is 15 miles (24 km) with an effective range of 11 miles (18 km) for artillery and 15 miles (24 km) for rockets. Its azimuth sector is 90°. It operates in the X-band at 32 frequencies. Peak transmitted power is 23 kW, min. It features permanent storage for 99 targets, has a field exercise mode and uses a digital data interface.
Pulse-Doppler radar sensors are therefore more suited for long-range detection, while FMCW radar sensors are more suited for short-range detection. Monopulse : A monopulse feed network, as shown in Fig. 2, increases the angular accuracy to a fraction of the beamwidth by comparing echoes, which originate from a single radiated pulse and which ...
"Critical" fire weather conditions could pick back up on Wednesday, January 22, and remain in effect until Saturday, January 25, as another round of Santa Ana Winds sweeps across Southern California.
Range and velocity can both be identified using medium PRF, but neither one can be identified directly. Medium PRF is from 3 kHz to 30 kHz, which corresponds with radar range from 5 km to 50 km. This is the ambiguous range, which is much smaller than the maximum range. Range ambiguity resolution is used to determine true range in medium PRF radar.
Pulse compression is a signal processing technique commonly used by radar, sonar and echography to either increase the range resolution when pulse length is constrained or increase the signal to noise ratio when the peak power and the bandwidth (or equivalently range resolution) of the transmitted signal are constrained.

The maximum range of conventional radar can be limited by a number of factors: Line of sight, which depends on the height above the ground. Without a direct line of sight, the path of the beam is blocked. The maximum non-ambiguous range, which is determined by the pulse repetition frequency. The maximum non-ambiguous range is the distance the ...
