Comparative Study of Four Different Types of MTI Filters for Radar Clutter Rejection

By Priyabrata Karmakar Sourav Dhar Mithun Chakraborty Tirthankar Paul

DOI:, Pub. Date: 28 Apr. 2013

In this paper MTI filter based clutter rejection technique is presented. How clutter rejection ability increases with the increase in Delay line canceleres in the MTI filter structure is shown here. Feedback path increases the response of a MTI filter and using feedback path four different types of MTI recursive filters are designed and tested for Radar clutter rejection. Matlab (7.9) is used as the simulation platform.

Application of Artificial Neural Network for Clutter Rejection

By Priyabrata Karmakar Sourav Dhar Mithun Chakraborty Tirthankar Paul

DOI:, Pub. Date: 8 Sep. 2012

This paper deals with application of Artificial Neural Network (ANN) for Radar Clutter rejection, function approximation method of supervised ANN is applied here using back propagation algorithm. The database used for training and testing the ANN has been collected from simulating a moving vehicle in MATALAB(version 7.9) to obtain the RCS values at range and cross-range profiles. This work is validated by comparing received signal after clutter rejection with the received signal in no clutter condition.

Fast Vertical Handover Algorithm for Vehicular Communication: A Holistic Approach

By Sourav Dhar Shubhajit Datta Rabindra Nath Bera Amitava Ray

DOI:, Pub. Date: 8 Apr. 2012

Next generation vehicular communication environment will consist of heterogeneous radio access networks (RAN). For seamless connectivity, vertical handover is a mandatory requirement. A novel context aware vertical handover algorithm is presented here. TOPSIS (Technique for Order Preference by Similarity to Ideal Solution), which is a multi criteria decision making (MCDM) tool, is used for the development of algorithm and MATLAB/SIMULINK is used as simulation platform. The optimum network is selected, based on multiple factors such as network traffic load, velocity of mobile station, data rate, usage cost and initial delay of network, among the available networks such as WiMax, WLAN and UMTS. This algorithm has been tested by simulating a virtual road traffic scenario. Variations in optimum RAN selection with vehicle speed keeping network traffic load constant and RAN selection with network traffic load keeping vehicle speed constant are shown graphically. The proposed algorithm is very simple yet powerful compared to the existing VHO algorithms and hence requires less execution time.
