以下是MATLAB仿真代码：

% 雷达参数
fc = 1e9;                   % 工作频率
c = 3e8;                    % 光速
lambda = c / fc;            % 波长
T = 1e-6;                   % 发射信号时宽
BW = 1e9;                   % 带宽
fs = 2e9;                   % 采样频率
PRI = 10e-6;                % 脉冲重复周期
R = [75e3, 50e3];           % 目标距离
v = [-100, -80];            % 目标速度
PRT = PRI / 10;             % 脉冲重复时间

% 发射信号
f0 = fc - BW / 2;
f1 = fc + BW / 2;
K = BW / T;
t = 0:T:2*T;
s = exp(1j*2*pi*(f0*t+K/2*t.^2));

% 接收信号
tau = 2 * R / c;
fD = 2 * v / lambda;
y = zeros(1, length(s) + length(tau));
for i = 1:length(R)
    y(length(s)*(i-1)+1:length(s)*i) = s.*exp(-1j*2*pi*(f0*tau(i)+(K/2)*tau(i)^2)).*exp(1j*2*pi*(BW/2/T*(t-T/2-2*R(i)/c).^2+f1*tau(i))).*sinc(BW*(t-2*R(i)/c-tau(i)));
end
y = awgn(y, 10, 'measured');

% 脉冲压缩
B = BW / 2;
N = T * fs;
t = linspace(-T/2, T/2, N);
w = 2 * pi * B / T;
h = exp(1j*pi*w*t.^2);
s = conj(fliplr(s));
H = fft(h, fs);
Y = fft(y, fs);
Z = Y .* H;
z = ifft(Z);

% MTI/MTD
P = 8;
W = 1 - exp(-1j*2*pi*(0:P-1)/P)';
Z = repmat(z, P, 1);
Z = Z .* repmat(W, 1, length(z));
Z = abs(Z).^2;
Z = sum(Z, 1);
Z = circshift(Z, [0,-P/2]);
v = diff(Z);

% 目标探测
Rmax = c/2/PRI * (1-sqrt(1-(BW*PRI)^2));
range_gate = round(Rmax * fs / c);
vel_gate = round(BW / (lambda * PRT));
M = ceil(length(v) / vel_gate);
N = ceil(length(z) / range_gate);
Pd = zeros(M, N);
for i = 1:M
    for j = 1:N
        v1 = (i-1)*vel_gate + 1;
        v2 = i*vel_gate;
        r1 = (j-1)*range_gate + 1;
        r2 = j*range_gate;
        x = v(v1:v2);
        y = z(r1:r2);
        Pd(i,j) = sum(abs(fftshift(ifft(x.*conj(y)))).^2);
    end
end

% 参数估计
[~, idx] = max(Pd(:));
[i, j] = ind2sub(size(Pd), idx);
R_est = (j-1) * range_gate * c / fs;
v_est = (i-1) * vel_gate * lambda / PRT;

注意，这只是一个简单的完整链路雷达信号处理MATLAB仿真，实际应用中还需要根据具体场景进行调整和优化。
