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 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.
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
Other innovations were radars with frequency hopping; the P-10 Volga A (NATO: KNIFE REST B) in 1953, radars with transmitter signal coherency and special features like moving target indicator (MTI); the P-12 Yenisei (NATO: SPOON REST) in 1955 as well as the P-70 Lena-M with chirp signal modulation in 1968 [2] or the widely used P-18 Terek (NATO ...
The AN/APG-68(V)9 [6] radar system consists of the following line-replaceable units: Antenna; Medium Duty Transmitter (MDT) Modular Receiver/Exciter (MoRE) Common Radar Processor (CoRP) The AN/APG-68(V)9 radar is the latest development. Besides the increase in scan range compared to the previous version, it has a Synthetic aperture radar (SAR ...
The APG-63 was developed in the early 1970s and has been operational since 1973, and was installed on all F-15A/Bs. [1] In 1979, it received a major upgrade and became the first airborne radar to incorporate a software programmable signal processor (PSP), and the PSP allowed the system to be modified to accommodate new modes and weapons through software reprogramming rather than by hardware ...
As a tactical radar, the ELM 2084 is a mobile system consisted of the radar unit, a control module, a cooling unit and a power generator. It can be mounted on a variety of transport platforms. The radar was designed to accommodate medium range operational needs in the battlefield: detection, classification and tracking of targets.
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.
