Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] The working module of the distance delay control circuit in this example includes target distance parameter, target speed parameter, dual-port RAM, ARM9 processor, distance delay pulse generation and FPGA signal processing.

[0024] The target distance parameter and the target speed parameter are used to set parameters in the radar target simulation system.

[0025] The dual-port RAM has two sets of completely independent data lines, address lines and read-write control lines on one SRAM memory, and allows two independent systems to simultaneously perform random access to the memory, with storage data sharing Etc. Used to store simulation parameters.

[0026] The ARM9 processor is a high-speed processor used for controlling and accessing simulation parameters and memory.

[0027] refer to figure 2 , the method of distance delay puls...

Abstract

The invention discloses a novel distance delay control circuit, which comprises a dual-port random-access memory (RAM) and a control module, wherein the dual-port RAM is used for outputting a distance delay pulse; the control module loads an embedded operating system and is used for accessing a selection control and memory unit of a simulation parameter; after a reference pulse is transmitted to the dual-port RAM, the distance delay pulse is obtained; and lastly, the control module accesses another set of data line, address line and read-write control line of the dual-port RAM so as to obtain the distance delay pulse and output the distance delay pulse. Compared with the prior art, the distance delay control circuit has the advantages of adjustable control parameter, high distance delay accuracy, high processing speed and the like.

Description

technical field [0001] The invention relates to the field of radar simulation control systems, in particular to a distance delay control circuit capable of simulating the generation of distance and speed in a radar system. Background technique [0002] Range delay is an important technology in the application of radar system target simulation, which is used to simulate various radar target signals and radar environments. At present, the radar system generally adopts field measurement.
