S301:Start timer, timing is set, timing is to then into next step;
S302:Pay close attention to be selected in target and aim in short distance from user and need the target of tracking, form tracking object listing, while will
Aim in short distance track association mark is set to not associated;
S303:Which of SSR antennas historical track and SSR platforms course according to aim in short distance, anticipation tracking target be in
In ripple position, it is the cnter wave Beam_center of the target to identify ripple position;
S304:The small sound calling sequence of layout;
S305:It is inquiry ripple position with Beam_center, launches small sound calling sequence;
S306:Judge whether the associated flag for tracking target is marked as having associated, next step is entered if having associated, otherwise
It is Beam_center-1, Beam_center+1, Beam_center-2, Beam_center+2, weight to change inquiry ripple position successively
Multiple step S305, until the associated flag of tracking target is marked as having associated or is tied from the inquiry of Beam_center+2 ripples position
Beam just enters next step;
S307:Judge whether the tracking target in list has asked, next step is entered if having asked, if also target is not compiled
Row's tracking inquiry, then return to all step S303;
S308:Using the small sound calling sequence parameter in step S304, the region layout inquiry ripple being likely to occur to aim in short distance
Position, carries out aim in short distance search inquiry;
S309:Aim in short distance flight path to successful association carries out relevant treatment and position filtering treatment, updates flight path state;
S310:Aim in short distance flight path to failed association carries out extrapolation process, updates flight path state;
S311:Return to step 301;
The concern target A codes that the user is set are specified or the cancellation of A codes for A codes.
6. target acquiring and tracking processing method according to claim 5, also includes between the S101 and S102:Judge
Whether A codes are legal, if yes then enter S102, if it is not, then returning to S101.
7. whether target acquiring and tracking processing method according to claim 6, judges the legal specific method of A codes
For:Judge whether A code values exceed [0,4096] scope, if it is, it is illegal, if it is not, then legal.
8. target acquiring and tracking processing method according to claim 5, the method between the step S310 and S311
Step also includes:Delete the aim in short distance flight path of continuous 3 secondary association failure;Answering point mark to failed association carries out new flight path
Starting.
9. target acquiring and tracking processing method according to claim 1, methods described also includes, sets target following excellent
First level is from high to low:User's concern target of setting, the aim in short distance set apart near non-user, apart from remote non-user
The aim in short distance of setting.Target is paid close attention to for the user that user is set, the target A codes priority being input into afterwards is higher than what is be first input into
Target A codes;The aim in short distance (being both not provided with specifying, be also not provided with cancelling) being not provided with for user, apart near priority
Higher than apart from remote.
10. target acquiring and tracking processing method according to claim 5, the small sound calling inquiry sequence is 24 steppings
Or the small sound calling inquiry sequence of other steppings;When carrying out layout using the small sound calling inquiry sequence of 24 steppings, it is assumed that former SSR's
Inquiry and beam transmission power are P Σ, inquiry control wave beam transmission power P Ω, and inquisitor receiving sensitivity is M, receives dynamic
Scope is D, then the small sound calling sequence parameter of 24 steppings is:When i-th stepping (i=1,2,3 ... 23,24) is inquired, inquire and wave beam
Transmission power be P Σ -42-i, inquiry control wave beam transmission power for P Ω -42-i, receives and beam signal level, reception are poor
Beam signal level and receive control wave beam signal level and decay (7+i) dB, answer signal decoding threshold is M+D-12.Work as i
During equal to 24, the transmission power of S1 pulses is 0;When i is not equal to 24, transmission power the taking for P Σ -42-i-x, x of S1 pulses
It is worth and is:When i is odd number, x=3;When i is even number, x=2.
