Embodiment

Below in conjunction with accompanying drawing, the present invention is described in detail.

As shown in Figure 1, a kind of signal processing apparatus of estimating based on soft data support target, comprises that interconnective target device 3-4, multilevel objectives estimating system, soft data support base management system and external unit 3-7; In described multilevel objectives estimating system, signal processing module 3-1, stimulating module 3-2, receiving and transmitting front end module 3-3 and receiver module 3-5 connect to form successively a loop and are connected with same interface control module 3-6 respectively; The external target device 3-4 of described receiving and transmitting front end module 3-3; The external soft data of described interface control module 3-6 is supported base management system 2-4 and external unit 3-7.

In the present invention, data flowchart as shown in Figure 2.When carrying out passive assessment, the modulation signal that echo signal source 2-1 sends directly converts digital signal to through receiving cable 2-2 and delivers to and in signal processing module 3-1, carry out signal and process 2-3, and signal processing module 3-1 completes target by the support of outside soft data storehouse 2-4 and estimates to resolve; If active sensor, needs to use transmission channel 2-5, by first launching the closed-loop process receiving again, complete the estimation to target.

As shown in Figure 3, described multi-layer target estimating system inside also comprises three functional modules such as information analysis characteristic module 1-1, characteristic vector sequence matching module 1-2 and semantic information evidence judging module 1-3, and described soft data is supported to comprise and this three functional module characteristic of correspondence data knowledge library module 1-4, priori features vector set library module 1-5 and semantic constraint condition library module 1-6 in base management system.

As shown in Figure 4, Figure 5, the chip that described signal processing module 3-1 comprises FPGA, DSP, DSP external memory bus and has transmitting-receiving agreement, level conversion, isolation and driving function, between described FPGA and chip, exchange channel data and control signal and provide clock signal for DSP, exchange agreement data between described DSP and chip, described signal processing module 3-1 is connected with transmission channel, receiving cable and external unit 3-7.

FPGA is responsible for providing channel module interface, and transceiver channel data also complete coding and decoding, transmits control signal, simultaneously for DSP provides clock to channel module; The management, multi-layer target that DSP is responsible for device interior soft data estimate judgement and and external unit between message exchange.

FLASH in signal processing module 3-1, SDRAM, FPGA are all hung in DSP peripheral hardware memory bus, by data/address bus, conduct interviews.FLASH is used for storing target signature knowledge base data, and SDRAM, for storing when the required target feature vector collection of subtask and constraint condition database data, also needs target signature knowledge base data to move to SDRAM from FLASH, to promote operation efficiency under duty.Signal processing module 3-1 manages by DSP/BIOS operating system, realizes command analysis, task triggering, state control.
