Abstract : Self-detect Collision Avoidance System, is a system equipped on an aircraft that identifies the signal strength between the aircrafts. The goal of SDCA is to prevent mid-air collisions between aircraft operating within the same airspace, by warning pilots of equipped aircraft that may present a collision threat. SDCA operates independently of Air Traffic Control by communicating with other aircraft to build a Received Signal Strength Indicator of aircraft in the same airspace. The RSSI is a measure of the RF power input to the transceiver. The RSSI value is based on the gain setting in the receiver chain and the measured signal level in the channel. By extrapolating the current range and altitude difference to anticipated future values, SDCA determines the potential of a collision threat. In this paper, SDCA and RSSI has been used to avoid collision between aircrafts which is the need of the hour because air traffic has become more tedious than road traffic. As this project is simple and cost efficient than the existing technology, it can be implemented in all the flights which makes it an added advantage.
