Fast Implementation of Transmit Beamforming for Colocated MIMO Radar

Multiple-input Multiple-output (MIMO) radars benefit from spatial and waveform diversities to improve the performance potential. Phased array radars transmit scaled versions of a single waveform thereby limiting the transmit degrees of freedom to one. However MIMO radars transmit diverse waveforms from different transmit array elements thereby increasing the degrees of freedom to form flexible transmit beampatterns. The transmit beampattern of a colocated MIMO radar depends on the zero-lag correlation matrix of different transmit waveforms. Many solutions have been developed for designing the signal correlation matrix to achieve a desired transmit beampattern based on optimization algorithms in the literature. In this paper, a fast algorithm for designing the correlation matrix of the transmit waveforms is developed that allows the next generation radars to form flexible beampatterns in real-time. An efficient method for sidelobe control with negligible increase in mainlobe width is also presented

Feminism in Poems of Manushya Puthiran

The skill of a writer is revealed in the language and style he uses. The way he expresses his thoughts is the basis for his works. The language used by the creator is the only proof for his skills, when poetry and prose flourish through the medium of language. Puthukavithai is a collection of poems which totally differs from old style and it broke the tradition of grammar and got published after facing many struggles.

The Virtues shown by Rama in the Nalaiyira Divya Prabandham

Virtue, wealth, happiness, and home/body are considered important for the lives of the people of the world. The first of them is a virtue. Morality is essential for individual life. All Tamil literature is based on the emphasis on morality. In Ramaavatharam, the incarnation of Tirumal, in his way of life, it is mentioned in the article on the virtue of Rama in his life, about his love and brotherhood without getting angry, to make sacrifices with love and brotherhood, to be friendly with good people, and to the manner in which he attains the Lord in the way of grace, and the manner in which he attains to the Lord in the way of grace, and the manner in which Rama has performed a hymn in his life, and how the Azhwars composed the hymns of the Lord as their refuge. The morality of the eleven scriptures found in the Pathinen Kilkanakku books is explained as evidence. The concepts of virtue and the semantic explanation of virtue are given. The virtues found in the shrines where the Azhwars sang imagining Thirumala as Rama is explained

Folk Literature in Nalayira Divya Prabandham

Folk literature is the mirror of society. Folk literature reflects the experiences and feelings of the rural people. The customs, rituals, ceremonies and traditions of the country people are expressed in folk literature. The nature of folk literature is seen in many ways. One of them is Nalayira Divya Prabandham, the Vaishnava literatry work. The Alwars composed hymns describing the virtues of Tirumal's marriage and incarnations and showed it up in folk literature. Alwars also sung many lullabies. They have sung a folk song called "Pallandu Vaalththu”. The nature of a woman who is in love with God can be known through the proverbs. Alwars have shown that they celebrated festivals two thousand years ago itself. The repetition of a word in folk literature is one of its characteristics. The opinions of scholars related to folklore are explained in this article. This article reflects the nature of folk literature in Nalayira Divya Prabandham
