Radio Detection And Ranging (RADAR) are remote sensing system with military, scientific and commercial applications. EM wave are sends by the radio detection and ranging in which we use the radio wave to find the “the distance metallic objects”. In the laboratory disclose the earlier results in the development of radar network. Some development of radar are given below a. Wave form design and diversity. b. Radar network. c. MIMO Radar. d. Navigation and positioning. e. Target detection and tracking. f. Sensor fusion. g. Routing. h. Security and privacy. i. Network capacity.
