The probability of detecting a given target at a given range any time the radar beam scans across it, Pd is determined by factors that include the size of the antenna and the amount of power it radiates. A large antenna radiating at high power provides the best performance. For high quality information on moving targets the Pd must be very high.
The REL－6B Radar is a ground-air surveillance and guidance radar ... Use digital 3 pulses or 4 pulses MTI to suppress noise; Output power element of transmitter is ...
AN/APS-21 search radar by Westinghouse Electric (1886) for part of AN/APQ-35 for Douglas F3D Skynight and Gloster Meteor NF; AN/APS-23 search radar by Western Electric for Convair B-36 North American B-45C Tornado Boeing B-47E Stratojet B-50 Superfortress B-52 Stratofortress Lockheed C-130 Hercules and Boeing C-135 Stratolifter part of AN/ASB-3
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 ...
CETC YLC-18 3D Radar – Sri Lanka Air Force. The YLC-2 radar (domestic designation: LLQ303, formerly known as 385) is a three-dimensional main guidance and surveillance radar developed by the Nanjing Research Institute of Electronics Technology. In the mid-2000s, an improved version labeled YLC-2A was deployed to the PLA.
A simple calculation reveals that a radar echo will take approximately 10.8 μs to return from a target 1 statute mile away (counting from the leading edge of the transmitter pulse (T 0), (sometimes known as transmitter main bang)). For convenience, these figures may also be expressed as 1 nautical mile in 12.4 μs or 1 kilometre in 6.7 μs.
A multibeam antenna assembly, mounted on the transmitter/receiver shelter and rotating at 3/6 rpm, is employed to form a group of stacked beams. RF power is generated by two transmitters and is fed to a power dividing network and then illuminated to the reflector via a waveguide assembly and feed array, creating a group of individual beams ...
The AR-320 is a 3D early warning radar developed by the UK's Plessey in partnership with US-based ITT-Gilfillan.The system combined the receiver electronics, computer systems and displays of the earlier Plessey AR-3D with a Gilfillan-developed transmitter and planar array antenna from their S320 series.
