Embodiment Construction

[0054] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0055] The present invention provides a radar communication integrated waveform design method based on multi-objective antlion optimization, the flow diagram is as follows figure 1 shown, including the following steps:

[0056] Step 1: Establish the fitness function of radar communication integrated waveform design.

[0057] The radar communication integrated signal adopts OFDM technology. According to the OFDM technology, the length of one OFDM symbol in the signal is first determined as T s =T g + T, T g is the length of the cyclic prefix, and T is the basic symbol duration. The subcarrier spacing can be obtained The number of subcarriers is N c , then the bandwidth of the integrated signal is B s =N c Δf. Communication information is included in OFDM symbols, and radar signals need to exist in the form of pulses, so there are two co...

Abstract

The invention relates to a radar communication integrated waveform design method based on multi-objective antlion optimization, comprising: establishing a radar communication integrated waveform design fitness function; initializing ant populations and antlion populations, and determining the number of multi-objective antlion optimization iterations; Initialize the fitness value of each ant, initialize the position of the elite antlion; update the position of the ant; calculate the fitness value of the ants in the population; update the storage space, and deal with the situation that exceeds the capacity of the storage space; update the position of the antlion and the position of the elite antlion; judge Whether the number of iterations of multi-objective antlion optimization is reached, if reached, stop the search, and randomly select a set of Pareto optimal solutions as the integrated waveform parameters; otherwise, repeat the execution. The invention considers the range of the blind area and the information transmission rate in the application of the integrated waveform, and can better meet the needs of actual engineering. During the evolution of ants, there are antlions and elite antlions to guide them together, effectively avoiding falling into local optimum during the optimization process. Improve convergence accuracy.

Description

technical field [0001] The invention relates to a radar communication integrated waveform design method, in particular to a radar communication integrated waveform design method based on multi-object antlion optimization, which belongs to the technical field of radar and wireless communication. Background technique [0002] In modern combat systems, various radar communication electronic equipment are more and more widely used, which greatly improves the combat capability of the platform. However, due to the complexity of electronic equipment, the system is bulky, energy consumption increases, and electromagnetic compatibility deteriorates. And other issues. In order to solve these problems, an integrated radar and communication system (IRCS) can be constructed to organically combine radar and communication equipment, thereby reducing the use of various electronic equipment. Combining radar and communication systems can give full play to their respective advantages, make up...
