In specific implementation process, the measurement method of parameters of described mobile target may apply to microwave radar or other In close application platform, one schematically illustrate here, just differ.In the embodiment of the present application, by the parameter with described mobile target As a example by measuring method is applied in microwave radar, the method in the embodiment of the present application is described in detail.

Before measurement method of parameters in the embodiment of the present application is described in detail in detail, first to the radar used in the embodiment of the present application Signal is introduced.

One frame of the radar signal used in one of radar process cycle as the embodiment of the present application, its time is a length of T_frame, is made up of the pulse repetition period that N number of cycle is T_PRI inside it, and inside each T_PRI, signal transmission time is T_fa, remaining time is the reception time, and concrete sequential is as shown in Figure 2.Wherein, T_fa is the fire pulse width of radar signal, The repetition period T_PRI of train of pulse adds the signal width of train of pulse equal to the ranging time of the detection range interested of microwave radar Degree.The dutycycle of train of pulse can be set according to detection range, as detection range is the longest, then controls the dutycycle of train of pulse The biggest；Detection range is short, then the dutycycle controlling train of pulse is little.

, being made up of M subpulse inside each train of pulse of radar signal, often group subpulse uses identical design meanwhile Mode, can use the linear frequency modulated waveform that identical initial frequency, same band are wide with time identical, it is possible to use identical two-phase to compile The modes such as code, as shown in Figure 3.

In specific implementation process, in order to improve the accuracy of parameter measurement, with the width of subpulse as T₂, train of pulse Repetition period T_PRI is T₂2ⁿTimes.

When method in using the embodiment of the present application carries out parameter measurement, step S101 is first carried out, it may be assumed that with first Penetrating N number of first pulsed radar signal of periodic emission, wherein, N is the integer more than or equal to 2.

In the embodiment of the present application, the described first transmitting cycle is to preset detection time and the summation of described duration.

In specific implementation process, as a example by the measurement method of parameters of described mobile target is applied in microwave radar, when When needing to use microwave radar to detect the mobile target in surrounding, the signal transmitter of microwave radar will be solid with one Fixed cycle sends above-mentioned N number of train of pulse.In described N number of train of pulse the duration of each pulse can be 24us, 30us or 100us etc., are not restricted.The duration that the transmitting cycle is each pulse of described N number of train of pulse The ranging time of detection range interested with maximum.Described ranging time needs the maximum operating range paid close attention to according to microwave radar Scope determines.As, microwave radar maximum can pay close attention to the target apart from itself 150km, then ranging time is 150km/ 0.15km=1000us.If the duration of each pulse is 24us, thus control the signal transmitter of microwave radar with the cycle Described N number of train of pulse is launched for 1024us.

After having performed step S101, the method in the embodiment of the present application just performs step S102, it may be assumed that at described N In individual first pulse signal in the duration of each first pulse signal, launch periodic emission M the second pulse thunder with second Reaching signal, wherein, described second launches the cycle launches the cycle less than described first, and wherein, M is the integer more than or equal to 2.

In the embodiment of the present application, the M integer power less than 2.

In specific implementation process, continue to use above-mentioned example, when the signal transmitter of microwave radar is sent out with the cycle for 1024us When penetrating described N number of train of pulse, in the duration of each pulse, signal transmitter also will launch periodic emission M with second Individual sub-pulse signal.In specific implementation process, in order to improve the accuracy of measurement and meet resolving requirement, M will be less than 2ⁿIt is individual, And second the transmitting cycle be less than for the first transmitting cycle.As a example by the duration of subpulse is as 1us, due to holding of each pulse A length of 24us time continuous, therefore, signal transmitter needs to send 24 subpulses in the duration of each pulse.Due to altogether Have sent N number of pulse, then corresponding subpulse number is N*M.

After having performed step S102, the step in the embodiment of the present application just performs step S103, it may be assumed that based on reception N number of first radar signal reflected corresponding with described N number of first pulsed radar signal arrived, obtains and is used for characterizing destination object Location parameter relative to described electronic equipment.

In the embodiment of the present application, refer to Fig. 4, the specific implementation of step S103 is as follows:

S401: taking i successively is 1 to N, obtains i-th the first pulse thunder launched in described N number of first pulsed radar signal Reach the launch time of signal, when i is N, obtain N number of first launch time；

S402: taking i successively is 1 to N, obtains and i-th the first pulse radar in described N number of first pulsed radar signal The i-th launch time of i-th the first radar signal reflected that signal is corresponding, when i is N, when obtaining N number of first arrival Between；

S403: based on described N number of first launch time and described N number of first time of advent, obtains and is used for characterizing target pair As the location parameter relative to described electronic equipment.

In specific implementation process, continuing to use above-mentioned example, the first pulse thunder launched by the signal transmitter at microwave radar After reaching signal and subpulse signal, if after radar signal detects destination object in investigative range, radar signal will return to Receiver, now, receiver will receive the N number of echo-signal corresponding with the first pulsed radar signal.Then, microwave radar Processor obtain transmitter and launch the launch time of described N number of first pulsed radar signal, and receiver receives described N Reception time during individual echo-signal, described N number of launch time and described N number of reception time are processed, so that it is determined that go out Destination object and the relative distance of microwave radar.Owing to the time interval between described N number of first pulsed radar signal is longer, thus Range ambiguity can be prevented effectively from.

In the embodiment of the present application, the specific implementation of step S403 is as follows:

In specific implementation process, continue to use above-mentioned example, when the processor of microwave radar obtains N number of launch time and N number of After the reception time, just obtain the transmitting of each pulse and reception time difference in described N number of first pulsed radar signal, with N As a example by being 3, it is 5us that the processor of microwave radar obtains the time difference of first pulse, time difference 4.8us of second pulse, The time difference of the 3rd pulse is 5.2us, in the way of then can being averaging to use weighting, obtains the meansigma methods of 3 time differences, Such as (5+4.8+5.2)/3=5us, thus obtaining destination object relative to the position of microwave radar is 3*10⁸*5*10^-6/ 2= 750m。

Certainly, those skilled in the art can also adopt and obtain target pair by radar signal and echo-signal in other ways The positional information of elephant, is not restricted.

S502: based in described K the second pulsed radar signal and described K the second radar signal reflected, obtain second Doppler frequency dimension；

S503: based on described first Doppler frequency dimension and described second Doppler frequency dimension, obtain described target The movement velocity of the most described electronic equipment of object.

In specific implementation process, continue to use above-mentioned example, after radar signal detects destination object in investigative range, Radar signal will return in receiver, and now, receiver can not only receive corresponding with the first pulsed radar signal N number of Echo-signal, moreover it is possible to receive the sub-echo-signal corresponding with N*M sub-pulsion phase.Then, the processor of microwave radar then base In N number of first pulsed radar signal and N number of echo-signal, form a Doppler frequency dimension at a slow speed；And based on N*M subpulse And N*M sub-echo-signal, forming a quick Doppler frequency dimension, the mode finally using double frequency territory to resolve obtains target pair The velocity information of elephant.Owing to the repetition period of N*M subpulse is shorter, frequency is high, and corresponding does not obscures speed greatly, but frequency is divided Resolution is relatively low；The repetition period of N number of first pulsed radar signal is longer, and frequency is low, and corresponding not obscure speed little, but frequency is divided Resolution is higher, thus the Doppler between available subpulse resolves the low resolution bigness scale realizing speed, utilizes between different pulse Doppler resolve and realize the high-resolution of speed and accurately measure, rough and accurate two gears match the incompatible survey completing frequency Amount.

In the embodiment of the present application, refer to Fig. 6, the specific implementation of step S501 is as follows:

S603: receive frequency based on described N number of first tranmitting frequency and described N number of first, obtain the first Doppler frequency Dimension.

In specific implementation process, continue to use above-mentioned example, in radar signal returns to receiver, now, microwave radar Processor just obtain the tranmitting frequency of each pulse in N number of first radar pulse signal, i.e. the transmitter of microwave radar is launched Frequency during pulse, obtains N number of tranmitting frequency；Meanwhile, processor also will obtain each signal in N number of echo-signal and return reception Reception frequency corresponding during machine, obtains N number of reception frequency, is then based on the tranmitting frequency of each pulse and receives the difference of frequency Value, forms the dimension of Doppler frequency at a slow speed set up by N number of pulse, and wherein, the Doppler frequency value of each pulse constitutes the most Element in general Le frequency dimension.

In the embodiment of the present application, refer to Fig. 7, the specific implementation of step S502 is as follows::

S701: taking i successively is 1 to K, obtains i-th the second pulse thunder sent in described K the second pulsed radar signal Reach the second tranmitting frequency of signal, when i is K, obtain K the second tranmitting frequency；

S702: taking i successively is 1 to K, obtains the i-th second received in described K the second radar signal reflected and reflects thunder Reach the second reception frequency of signal, when i is K, obtains K second and receive frequency；

S703: receive frequency based on described K the second tranmitting frequency and described K second, obtain the second Doppler frequency Dimension.

In specific implementation process, continue to use above-mentioned example, in radar signal returns to receiver, now, microwave radar Processor just obtain the tranmitting frequency of each subpulse in N*M subpulse, i.e. subpulse launched by the transmitter of microwave radar Time frequency, it is thus achieved that N*M tranmitting frequency；Meanwhile, each signal in acquisition N*M sub-echo-signal is also returned and connects by processor Reception frequency corresponding during receipts machine, obtains N*M and receives frequency, is then based on the tranmitting frequency of each subpulse and receives frequency Difference, form the quick Doppler frequency set up by N*M subpulse and tie up, wherein, the Doppler frequency value of each subpulse Constitute the element in quick Doppler frequency dimension.

In the embodiment of the present application, refer to Fig. 8, the specific implementation of step S503 is as follows:
