Abstract


The radar altimeter is essential equipment on a variety of aircraft, missiles and other flying body plays an important role in its flight safety, communications and navigation . Altimetry methods the pros and cons of the role of the radar altimeter , distance , ranging accuracy , reliability , and other indicators have a very important role the radar altimeter altimetry is very important . Pulse the system radar altimeter has the role distance measurement accuracy , strong anti-interference , suitable for a variety of aircraft . This paper studied the works of the pulse system radar altimeter , theoretical calculations based on the radar equation × × × hollow the altimeter role distance . Pulse leading edge tracking and detection technology , different from the previous traditional analog signal processing method , the first mathematical statistical methods in the altimetry principle and measuring high-precision altimeter measurement , analysis , and analysis of the various implementations advantages of the program , applicable environmental and models. The completed system design , design a circuit diagram , produce a printed circuit board , and the completion of the CPLD simulation and hardware and software debugging , the whole produce × × × hollow altimeter completed improvements WG × altimeter . The installed flight test results also confirmed the validity of the method .
