Method for generating digital combined pulse signals with continuous phase positions

Abstract

The invention belongs to the field of phased array radar resource scheduling, and relates to a sliding window resource scheduling technology based on sectors, in particular to a method for generating digital combined pulse signals with continuous phase positions. The technology is mainly suitable for resource management and distribution of a two-dimensional rotary phased array radar. A radar system carries out resource distribution on multiple functions and multiple tasks according to the sectors, and the residence time of various tasks is adjusted in the sectors in a self-adaptive mode according to loads of the tasks. According to the sliding window resource scheduling technology, when resource distribution is carried out on a current scheduling interval, the task load condition of one sector starting from the current scheduling interval is considered, the task load of one sector starting from the next interval is considered when the next scheduling interval is carried out, and sliding window type resource scheduling is formed. The residence time distribution ratio of the various tasks is determined according to the different work modes of the radar, the detection range, the search data rate, the fine batch number, the determination batch number and the like of the radar are adjusted in a self-adaptive mode according to the time obtaining the tasks, the multiple functions and the multiple tasks are achieved at the same time, and the flexibility and operational effectiveness of the two-dimensional rotary phased array radar are improved.

Description

technical field

[0001] The invention belongs to the radar signal generating technology, adopts the inter-pulse sinusoidal signal compensation method, ensures multi-pulse signals, inter-pulse phase continuity, and stable amplitude, and realizes the generation of digital combined pulse signals with continuous phases. Background technique

[0002] Solid-state transmitters have wide frequency bands and large duty cycles, and are widely used in radar systems. In the radar of conventional pulse compression system, the solid-state transmitter works as follows: receiving a pulse excitation signal and triggering a power output. Due to multi-stage amplification, the solid-state transmitter has a certain delay from triggering to stable power output, and the delay can be as long as more than 1us. During this delay, the output signal power rises slowly and cannot be used as a normal radar signal.
