Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0042] The present invention provides a radiation time control method of a radar communication integrated system based on time division multiplexing, such as figure 1 As shown, it specifically includes the following steps:

[0043] Step 1: Build an integrated radar communication system based on time division multiplexing.

[0044] like figure 2 As shown, the radar communication integrated system is composed of a radar communication integrated transmitter, a radar receiver and a communication receiver. The system adopts the time division multiplexing system to realize the functions of target detection and communication data transmission. Suppose the total radiation time of the integrated radar communication system is T, and the radiation power is P T , where the radiation time of the integrated radar communication system for realizing the radar function is...

Abstract

The invention discloses a radar communication integrated system radiation time control method based on time division multiplexing. The method comprises the steps: firstly constructing a radar communication integrated system which employs a time division multiplexing system to achieve the target detection and communication data transmission functions; secondly, representing the communication performance of the radar communication integrated system by adopting an information rate, representing the target detect ion performance of the radar communication integrated system by adopting a target detection probability and a false alarm probability, and respectively deducingrespective closed analytical expressions; and then, under the condition that the false alarm probability is given, taking a preset information rate threshold value and a target detection probability threshold value as constraint conditions, and taking minimization of the total radiation time of the radar communication integrated system as an optimization target, establishing a radar communication integrated system radiation time control model based on time division multiplexing, and optimizing the model. According to the invention, the total radiation time of the radar communication integrated system is effectively reduced, and the radio frequency stealth performance of the system is improved from the time domain.

Description

technical field [0001] The invention belongs to the technical field of radar signal processing, and in particular relates to a radiation time control method of a radar communication integrated system based on time division multiplexing. Background technique [0002] In order to meet the needs of the modern warfare environment under high-tech conditions, modern weapons and equipment need to be equipped with various types of radar equipment and communication equipment to complete the necessary battlefield situation awareness and tactical data link functions. As the two most common and important applications in modern radio technology, radar detection and wireless communication are independently designed and developed according to different functions and frequency bands. Among them, radar is mainly used for target detection, tracking and identification, and the purpose of communication It is to realize information transmission between platforms, but with the increasing number o...
