Abstract

The invention presents a high-speed missile-borne radar waveform designing method. One embodiment of the method comprises: limiting the synthetic bandwidth and determining its value by the distance resolution and the signal-to-noise threshold; giving the number of intra-frame pulses; determining the frequency step amount; determining the lower limit of the pulse repetition frequency and the upper limit of the pulse width; setting the initial value for the pulse width according to the limitation of the value range of the pulse repetition frequency; determining the value range and the value of the pulse repetition frequency; if the value range is an empty set, indicating that the initial value of the preset pulse width is unreasonable and re-setting an initial value for the pulse width; and determining the number of pulse accumulation points; determining the ultimately appropriate distance range by the non-fuzzy distance and blind distance. This embodiment, with the technologies of millimeter waves, large bandwidth, step frequency and duplex frequency, solves the problem that that a target passes off and deviates from a distance unit caused by the reduced signal-to-noise ratio, the main lobe clutter Doppler broadening and the high speed movement between the bombs, therefore, achieving the purpose of precision strikes.

Description

technical field [0001] The invention belongs to the field of radar technology, and relates to a method for suppressing clutter by using a signal system with high repetition frequency and large bandwidth. Anti-clutter ability. Background technique [0002] With the continuous development of science and technology and the continuous improvement of national defense requirements, the development of national defense weapons has gradually entered the information age. Rockets have the advantages of long range, simple launch platform, high lethality, and good maneuverability, so they have become an indispensable suppressive weapon in modern warfare. However, conventional rockets only have surface strike capability and cannot meet the requirements of long-range precision strike firepower. Therefore, since the 1990s, guided rocket technology has been rapidly developed and put into military use. Guided rockets can effectively improve the accuracy of hitting targets while ensuring ran...
