Phase-Array Radar and Synthetic-Aperture Radar (SAR).

The use of phased array can be made in radar applications for airborne fighter or attack radar applications. This is particularly possible through phased array radar that can be electronically steered (Skolnik, 2003, p.649). The concept behind phased array radar is that it makes use of the signal phases through its electronic controls. The phases are obtained at specific components of the array leading to generation of constructive interference in a path that is preferred for the positioning of the beams. Mechanical activities are not required in the process. Depending on each individual pulse, the radar beam can be steered, the time interval of such steering generally being 0.001s. The steering can be obtained in any desirable direction and in different angles. The flexibility of the beam steering is unlike other mechanical radars thus making the phased array radars unique and different from others. The stress generated on the pedestals, motors, and other parts of the radar can be reduced through methodical scanning of the radars following an uninterrupted model (Committee on the Evaluation of the Multifunction Phased Array Radar Planning Process, 2008, p.19). ...

Advantages of miniaturization Miniaturization is very vital as it has several advantages. It requires low cost, has the ability to accommodate greater density and it is high in speed. The small electronics are very faster as the signals they transmit travel over short distances and the devices do not travel for long distances within the implemented device. Furthermore, packing of small sized devices is quite advantageous as it help reduce the cost incurred in the electronics. For instance, though four times the memory capacity, a 1-megabit DRAM chip which contains 256-kilobit DRAM is less…

Design bandpass FIR digital filter to extract sub-Hz low frequency signal
The aim of this research work is to design and performance evaluation of 0.2 – 0.5 Hz Butterworth, Blackman and Chebyshev digital semi adaptive filters. For this work XILINX and MATLAB software’s were used for the design. As pert of practical research work these designs were translated Using FPGA hardware SPARTAN-3E kit. These were optimized, analyzed, compared and evaluated keeping the sampling frequency at 1Hz for 64 orders. These filters designed using software were tested by passing a sinusoidal test signal of 5 Hz along with noise and the filtered Output signals are presented. Signal…

On the other hand, the top-down approach of manufacture in nanotechnology allows creation of chip by taking away the mass material which is used for its design. This approach will not consider the usage of atomic structuring but it rather takes away the design of externality. Currently the employment and advancement has taken it toll in the top down method. It can be said that the other approach namely bottom up approach is still in its theoretical phase. There is much need of advancement in the applied approach of bottom-up. It is due to their reason that the nanotechnologists have made us of…

Super Heterodyne Receiver
All modern television and radio receivers virtually use the principle of super heterodyne. The super heterodyne receiver reduces to the same intermediate frequency value. In order to accomplish this, it requires that the super heterodyne receiver be able to vary incessantly the frequency that is being mixed into the signal in order to keep the same difference (Jerry 1172). This paper will discuss Super Heterodyne Receiver and its various aspects. History The history of Super Heterodyne Receiver can be traced back to 1905 when Reginald Fessenden, a Canadian inventor, described proposed method…
