[1] The operator hears the echoes from any reflection. Therefore, it performs transmission/listening continuously, which covers the space 360 °. The primary radar functions, therefore, results in detection and measurements of position if there is the presence of a target by the recognition of the useful signal. A primary radar measurement include:
SSR antenna of Deutsche Flugsicherung at Neubrandenburg, in Mecklenburg/Western Pomerania Transponder in a private aircraft squawking 2000. Secondary surveillance radar (SSR) [1] is a radar system used in air traffic control (ATC), that unlike primary radar systems that measure the bearing and distance of targets using the detected reflections of radio signals, relies on targets equipped with ...
This is possible since the reflective characteristics of humans are generally more diverse than those of the materials typically used in construction. However, since humans reflect far less radar energy than metal does, these systems require sophisticated technology to isolate human targets and moreover to process any sort of detailed image.
The EPC contractor coordinates all design, procurement and construction work and ensures that the whole project is completed as required and in time. They may or may not undertake actual site work. EPC companies are often used in large-scale projects, such as power plants, refineries, chemical processing facilities, infrastructure projects, and ...
The klystron tube transmitter operates in the S-band between 2.5 and 2.9 GHz in circular polarization with a peak power of 1.3 MW and a pulse duration of 1 μs and pulse repetition frequency between 325 and 1200 pps. It can be switched to a second reserve frequency if interference is encountered on the primary frequency.
Australian Construction Contracts govern how the parties to a construction contract behave and how the project manager and the contract manager administer the relationship between the parties. [1] There are several popular standard forms of construction contracts that are currently used in Australia .
[1] They are used by a construction manager who is working as an agent to the owner or by the owner itself to carry-out a construction project while mitigating the risks to the scope of work, time, budget, quality and safety of the project. These risks ranges from cost overruns, time delays and conflict among the various parties.
The difference between this type of contract which is a cost-based contract with lump-sum contract is that in guaranteed maximum price (GMP), if there is any savings resulted from cost under runs, then that would be stipulated price contract, and the contractors will keep the savings obtained from the cost under runs for themselves and there is ...
