Abstract
The invention discloses a real-time pulse azimuth detecting method and radar equipment. The method comprises the steps of generating n azimuth increment pulses which correspond with one response signal through an azimuth encoder of the radar equipment; determining a first azimuth parameter of the response signal through using a first measurement unit as a measuring standard based on the n azimuth increment pulses; furthermore obtaining a second azimuth parameter of the response signal through using a second measurement unit as a measuring standard, wherein the least unit measurement value of the second measurement unit is smaller than that of the first measurement unit; and finally obtaining an azimuth parameter with accuracy which is higher than measurement standard of an antenna azimuth disc. Therefore the real-time pulse azimuth detecting method and the radar equipment have a technical effect of improving azimuth measurement accuracy of the radar.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a real-time pulse azimuth detection method and radar equipment. Background technique [0002] The secondary radar system is a signal detection system including ground interrogation equipment and airborne transponder equipment, wherein the ground interrogation equipment uses monopulse angle measurement technology for azimuth measurement. The implementation process of this technology is as follows: by rotating the antenna to direct the beam When the directional beam points to the airborne transponder, the airborne transponder will receive the interrogation signal and transmit a response signal according to the agreed signal format, and the ground transponder can extract the corresponding response signal when receiving the response signal. The orientation of the azimuth code wheel, so as to determine the orientation of the answering device when sending out the answering signal. ...
