This paper describes one of the solutions RF oscillator radar to protect the car from collisions, which belong to the class of car radars that are very precisely defined norms and standards of work. This decision is based on the voltage controlled oscillator, which provides RF signal EM frequencies of the permitted range (23.6-25.6 GHz) and strength in the ISM band to 20 dBm with allowed elevation angle required signal / noise ratio of the receiving signal and angular resolution. Solution oscillator where simulated on a PC. A relatively narrow beam of either RF or optical electromagnetic radiation is scanned over a relatively wide azimuthal range. The return signal is processed to detect the range and velocity of each point of reflection. The idea that a lower false alarm rate might be achieved by a better form of signal processing that had been used to detect imminent crashes in earlier studies. Since many different heuristic strategies had all been tried without success, a radically different approach was thought to be needed. Recently, neural networks have received much acclaim for their ability to learn functional relations between two sets based on a sample data set. Such a device seemed like a solution to lower the high false alarm rate and perceive complex relationships between sensor data and collision prediction. [ABSTRACT FROM AUTHOR] |
