Radar communication integrated system and expansion method of system

Abstract

The invention discloses a radar communication integrated system and an expansion method of the system. The radar communication integrated system specifically comprises a radar with the distance of R2and a control center; wherein the radar is used for transmitting a radio frequency signal s1 (t), investigating a target observation interval with the distance of R1, receiving echo signals reflectedby N targets in the target observation interval, extracting position information from the echo signals and transmitting the position information to the control center; and the control center is used for carrying out data processing on the signal transmitted by the radar to obtain the position of the target. According to the capacity expansion method, when the total power is limited, the capacity of a radar communication system serves as an optimization objective function, power distribution is conducted on the radar system and a communication network, the position of a radar is reasonably planned, and therefore system capacity maximization is achieved. According to the invention, real-time communication can be realized, and under the condition of the same transmitting power, compared witha common radar system, the radar communication system provided by the invention can transmit more data.

Description

technical field [0001] The invention relates to radar technology, in particular to a radar communication integrated system and a capacity expansion method of the system. Background technique [0002] Radar is a transliteration of English Radar, the full name is radio detection and ranging, which means "radio detection and ranging", that is, to find targets and determine their spatial positions by radio. Radar emits electromagnetic waves to irradiate targets and receives their echo signals to obtain information such as the distance, elevation angle, azimuth and radial velocity of the target relative to the position where the electromagnetic waves are emitted. [0003] In the face of the ever-expanding scope of operations and the increasing complexity of the combat environment, radar technology continues to develop. With the emergence of various new technologies and new system radars, a single-mission radar can no longer adapt to the rapid changes in modern combat factors. Th...

Problems solved by technology

Currently, existing radar models such as figure 1 As shown, the fixed radar at the control center emits electromagnetic wave signals to detect the observation interval with a distance of R. The N targets in the observation interval reflect electromagnetic waves, and there is no upward shielding between them, and the radar receiver extracts the echo The useful information in the signal is directly processed by the control center, but the data obtained by the radar generally needs to be manually recorded and then notified to the rear through wired or radio, so there are defects such as slow information transmission, poor confidentiality and false alarms

The airborne communication station also has the problems of slow transmission speed and small transmission capacity. For example, after the aircraft collects a large amount of data, the existing data link cannot transmit the data back to the ground in time.
